Hi!
There definitely is a delay between the time
the signal is raised and the moment when the
handler-routine is invoked. It is not possible
to execute the handler asyncronously. This
works ok if the signals are not sent in rapid
succession, but breaks down if they are. I currently
know of no decent way to address this problem.
Perhaps one could maintain a list of forked
child-processes and regularly (or if a SIGCHLD
occurs) check wether they are zombies (ps does this,
so it should be possible (?)).
cheers,
felix
