Trapping Real Time Signals in ZSH

Trapping Real Time Signals in ZSH

[bagnaramatt]

In bash the trap builtin is able to handle all signals including SRTMIN-
SIGRTMAX. In ZSH the kill builtin dos not provide the ability to utilize all
of there signals. Is there any supported way to handle trapping real-time
signals in ZSH?

Currently there is not.  The scripts in the build process that extract
signal names from the system headers do not recognize SIGRTMIN or or
SIGRTMAX, and the faux signals SIGZERR and SIGDEBUG may overlap with
the range of realtime signals.

However, it's possible to send any of these signals by number with the
kill builtin, even though "kill -l" doesn't list them.
