* debugger/command-loop.scm: Prefix all commands imported from
(ice-9 debugger command-loop) with debugger:.
* boot-9.scm (resolve-interface): Process #:hide; Name custom interfaces
appropriately.
(module-use!, module-use-interfaces!): Remove existing interfaces
on the use-list based on module name rather than interface
identity so that custom interfaces truly replaces their previous
version.
(<class> <operator-class> <entity-class> <entity>): Marked as
replacements.
(upgrade-accessor): Renamed from upgrade-generic-with-setter.
(ensure-accessor, upgrade-accessor): Rewritten to accomodate the

SCM_EOL.
(scm_struct_prehistory): Move scm_free_structs to
scm_before_mark_c_hook.

this card before. That can happen if scm_i_sweep_all_segments has
been called from some other place than scm_igc.
(scm_struct_prehistory): Init scm_i_structs_to_free to SCM_EOL.
(This fixes a serious GC bug, introduced during the latest
reorganization of the GC, preventing freeing of structs and GOOPS
objects.)
(since hash tables now adapt their size).
* modules.c (scm_modules_prehistory): Changed from 2001 to 1533
(current number of prehistory bindings; hashtable code will select
a prime which is greater than this value).

calls to scm_storage_prehistory and scm_hashtab_prehistory.
* modules.c (module-reverse-lookup): Use hashtable accessors.

* weak-vector.scm: New file.
* boot-9.scm (module-clear!): Use hash-clear!.
(module-for-each): Use hash-for-each.
(module-map): Use hash-map.
futures. For fine-grained threading this lifts performance to
another level. We can now use parallelization in inner loops of
Guile programs without impossible overhead.
* psyntax.ss (self-evaluating?): Removed. Guile now provides this
operator as a primitive procedure.
(build-data): Quote vectors (psyntax.ss requires this).
compute-new-list-of-methods): Use methods slot directly instead of
generic-function-methods.
(upgrade-generic-with-setter): Handle <extended-generic>:s.

scm_gc_register_collectable_memory): Substitute locking of
scm_i_sweep_mutex for calls to scm_i_thread_put_to_sleep.
(scm_igc): Lock sweep mutex here instead of in callers; Calls to
scm_i_thread_put_to_sleep/scm_i_thread_wake_up used to demarkate
the single-thread section (which now only contains the mark
phase).
(scm_gc): Don't lock sweeo mutex here since scm_igc locks it;
Removed SCM_DEFER/ALLOW_INTS. Simply call scm_igc directly.
* threads.c (gc_section_mutex): Removed.
thread_admin_mutex in order not to risk being joined.
(scm_i_thread_put_to_sleep, scm_i_thread_wake_up): Keep
thread_admin_mutex locked during GC.
* pthread-threads.c, pthread-threads.h: Improvements to debugging
functions.
(thread_print): Print thread number as well as address of thread
structure.
(scm_join_thread): Bugfix.
(scm_lock_mutex, scm_try_mutex, scm_unlock_mutex,
scm_timed_wait_condition_variable, scm_signal_condition_variable,
scm_broadcast_condition_variable): Use the low-level API.
(scm_all_threads): Return copy of thread list (to prevent
unintended destruction).
(scm_threads_prehistory): Initialize heap_mutex of fake thread.
Simply lock a thread C API recursive mutex.

SCM_REC_CRITICAL_SECTION_END): Removed.
* eval.c: Replaced SOURCE_SECTION_START / SOURCE_SECTION_END with
direct calls to scm_rec_mutex_lock / unlock around the three calls

(scm_force): Rewritten; Now thread-safe; Removed
SCM_DEFER/ALLOW_INTS.
* pthread-threads.h: Added partially implemented plugin interface
for recursive mutexes. These are, for now, only intended to be
used internally within the Guile implementation.

* threads.c: Conditionally #include "pthread-threads.c".
* eval.c, eval.h (scm_makprom, scm_force): Rewritten to be
thread-safe;
* snarf.h (SCM_MUTEX, SCM_GLOBAL_MUTEX, SCM_REC_MUTEX,
SCM_GLOBAL_REC_MUTEX): New macros.
* eval.c, threads.c, threads.h, snarf.h: Rewrote critical section
macros---use mutexes instead.
* tags.h (SCM_IM_FUTURE): New tag.
* eval.c (scm_m_future): New primitive macro.
(SCM_CEVAL): Support futures.
