in reply to Do's and Dont's inside a signal handler

Do as little as possible, the more stuff you do the more chance that things are happening at an inconvieniant time for your application... interrupted syscalls etc

Basically, just set a flag that your application will check and reset next iteration through...

my $running = 1; $SIG{HUP} = sub { $running =0 } while ($running){ do_stuff(); }
the handler only signals the outside that next time through it should stop...
