version. * debug.cc (__set_errno): Ditto. * exceptions.cc (handle_sigsuspend): Remove spurious sig_dispatch_pending call. (set_signal_mask): When there seem to be pending signals to dispatch, tell signal_dispatch_pending/sig_send not to specifically call any handlers. * sigproc.h (sig_dispatch_pending): Change declaration to void. * sigproc.cc (sig_dispatch_pending): Change definition to void. Take an argument to determine whether to tell sig_send to wait for handler to be called. * sigproc.cc (sig_send): Don't call signal handler when sig == __SIGFLUSHFAST. (wait_sig): Honor __SIGFLUSHFAST. Guard against sigpacket::process nuking si_signo. * sigproc.h (__SIGFLUSHFAST): Define new special signal. (sig_dispatch_pending): Change declaration to void. Take optional boolean argument. * fork.cc (vfork): Add debugging output.
