handling whenever a '\' is detected. * signal.cc (sigaction): Make strace output more informative. * sigproc.cc (pending_signals::add): Just index directly into signal array rather than treating the array as a heap. (pending_signals::del): Ditto. (wait_sig): Don't send signal if we already have a similar signal queued. * sigproc.h (call_signal_handler_now): Remove obsolete declaration.
