Nothing to do with Perl.
Some system remove the handler once it has caught a signal. If you want your program to handle more than one instance of the signal on those platforms, you need to set the handler again in the handler.
I don't know what those systems are. Not your everyday systems. I think it's "SysV" systems, whatever that means.
