to be more precise, "... if handler was set with signal() call or
sigaction call with appropriate flag?"
linux man page for sigaction contains the followin text:
===============================================================
...
SA_ONESHOT or SA_RESETHAND
Restore the signal action to the default
state once the signal handler has been
called. (This is the default behavior of
the signal(2) system call.)
===============================================================
glibc doc, otoh, says that signal which is currently handled
should be blocked. susv2 says nothing specific. maybe someone
quote what posix or ansi say about this?
