* doc/ref/api-data.texi (Symbol Read Syntax): Mention the 'r7rs-symbols'
print option, and provide example code to enable both the read and
print options. Add 'r7rs-symbols' to the concept index.
* module/system/repl/error-handling.scm (call-with-error-handling): Add
#:report-keys kwarg, so that unwind-only exceptions (stack-overflow in
particular) get reported.
* doc/ref/api-debug.texi (Pre-Unwind Debugging): Add documentation for
#:report-keys kwarg of call-with-error-handling.
(Stack Overflow): New subsubsection.
(Debug Options): Remove discussion of stack overflow.
* doc/ref/posix.texi (Signals): Fix the documentation for setitimer; it
was wrong.
* libguile/scmsigs.c (pack_tv): New helper. Allow usecs >= 1e6.
(unpack_tv): New helper.
(scm_setitimer): Use the new helpers.
* test-suite/tests/signals.test: Add setitimer tests.
* libguile/libguile-2.0-gdb.scm: New file.
* libguile/Makefile.am (install-data-local): New target. Based on code
from GNU libstdc++.
(EXTRA_DIST): Add 'libguile-2.0-gdb.scm'.
* doc/ref/api-debug.texi (GDB Support): New section.
Modified-by: Mark H Weaver <mhw@netris.org>
* module/system/repl/coop-server.scm: New module.
* module/system/repl/repl.scm (start-repl): Extract body to start-repl*.
(start-repl*): New procedure.
(run-repl): Extract body to run-repl*.
(run-repl*): New procedure.
* module/system/repl/server.scm (run-server): Extract body to
run-server*.
(run-server*): New procedure.
* doc/ref/api-evaluation.texi (Cooperative REPL Servers): New node.
* module/Makefile.am (SYSTEM_SOURCES): Add system/repl/coop-server.scm.
* module/system/repl/server.scm: Import (ice-9 match) and (srfi srfi-1).
(*open-sockets*): Add comment. This is now a list of pairs with a
'force-close' procedure in the cdr.
(close-socket!): Add comment noting that it is unsafe to call this
from another thread.
(add-open-socket!): Add 'force-close' argument, and put it in the cdr
of the '*open-sockets*' entry.
(stop-server-and-clients!): Use 'match'. Remove the first element
from *open-sockets* immediately. Call the 'force-close' procedure
instead of 'close-socket!'.
(errs-to-retry): New variable.
(run-server): Add a pipe, used in the 'force-close' procedure to
cleanly shut down the server. Put the server socket into non-blocking
mode. Use 'select' to monitor both the server socket and the pipe.
Don't call 'add-open-socket!' on the client-socket. Close the pipe
and the server socket cleanly when we're asked to shut down.
(serve-client): Call 'add-open-socket!' with a 'force-close' procedure
that cancels the thread. Set the thread cleanup handler to call
'close-socket!', instead of calling it in the main body.
* doc/ref/api-evaluation.texi (REPL Servers): Add a caveat to the manual
entry for 'stop-servers-and-clients!'.

Deprecate. This interface lacked both generality and specificity.
The general replacement is array-length, array-ref, and friends on the
scheme side, or the array handle interface on the C side. On the
specific side of things, there are the specific bytevector, srfi-4,
and bitvector interfaces.

weak vectors are mainly useful for implementing weak hash tables.
