First, yes, I read the FAQ, I tried a handler on SIG{INT}.

I'm working on a script that runs rsync every few seconds and I'd like to be able to handle CTRL-C gracefully, which means letting rsync finish what it's doing before exiting.

Right now, rsync catches CTRL-C, not my script, so my script keeps running and rsync gets interrupted.

Here's a reeeealy short psudo-code version of my script

$SIG{INT} = \&blah;

sub blah {
    sleep 10;
    exit;
}

while (1) {
    system("rsync -a rsync://blah.example.com/foo foo");
    sleep 5;
}

Hmmmm... Writing this I think I see the problem. I need to fork off the rsync job somehow so my perl script will actually be running at the time it gets signalled...

What's the best way to handle that? (If I've got this figured out that is...)
