  • Makefile.am, configure.ac: Add test to address cases where a thread is waiting on a signal (sigwait) and we send it. Also address case where there are too many queued signals.
  • psxsignal03/.cvsignore, psxsignal03/Makefile.am, psxsignal03/init.c, psxsignal03/psxsignal03.doc, psxsignal03/psxsignal03.scn: New files.
