* psxsignal03/init.c, psxsignal03/psxsignal03.scn,
psxsignal04/psxsignal04.scn: Correct test numbers in macros so output
is right. Update both screens.
* Makefile.am, configure.ac, psxsignal03/Makefile.am,
psxsignal03/init.c, psxsignal03/psxsignal03.doc: Add new test
variation which focused on real-time signals rather than user
signals.
* psxsignal04/.cvsignore, psxsignal04/Makefile.am,
psxsignal04/psxsignal04.doc, psxsignal04/psxsignal04.scn: New files.
* 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.
