* libguile/scmsigs.c: Use raw pthread_create / pthread_join instead of Guile's scm_spawn_thread, to ensure that the thread is entirely stopped before a fork. * libguile/scmsigs.h (scm_i_is_signal_delivery_thread): New internal procedure, replacing a manual check against scm_i_signal_delivery_thread. * libguile/threads.c: Use the new procedure. Based on a patch by Rob Browning. Thanks!
