What sort of tasks/side effects are happening in the subroutines? You may be able to solve your issue with a fork, a la: `use strict; use warnings; if (my $pid = fork) { eval { local $SIG{ALRM} = sub{die "Timeout hit\n"}; alarm 1; wait; alarm 0; 1; } or do { print $@; kill 9, $pid; } } else { magick_die(); exit; } sub magick_die { my $var = 0; for (1 ... 1000000) { $var++ for 1 .. 1000000; } }` [download] If you need to pass information back and forth, you could serialize over pipes. #11929 First ask yourself `How would I do this without a computer?' Then have the computer do it the same way.	[reply] [d/l]

use strict;
use warnings;

if (my $pid = fork) {
    eval {
        local $SIG{ALRM} = sub{die "Timeout hit\n"};
        alarm 1;
        wait;
        alarm 0;
        1;
    } or do {
        print $@;
        kill 9, $pid;
    }
} else {
    magick_die();
    exit;
}


sub magick_die {
    my $var = 0;
    for (1 ... 1000000) {
        $var++ for 1 .. 1000000;
    }
}
