Brothers and Sisters,

Being new to programming Perl under Windows I am constantly running into things that don't work the same as they do under Unix (e.g. fork which I've pretty much finally got my head around).

Here's another one that I'm not so sure of. I've super-searched PM and Googled a little, but can't seem to find what I need to know. I need to make sure that when some kills my Perl script that it kills all of it's project. I.e., I want to turn a ^c from a user into the equivalent of Proc::Killfam::killfam 'TERM', $$. I have used the following code to try to accomplish this with mixed success: 

    use Win32::Process::Info;
    my $pi =  new Win32::Process::Info();
    $SIG{INT} = sub {
        local $SIG{INT} = 'IGNORE';        
        @children = keys %{$pi->Subprocesses($$)};  
        @children = grep $$ != $_, @children;
        kill 1, @children;
        exit;
    };

This seems to work sometimes, but not others. In particular this hangs when one of the children is 'stuck' some way, e.g. in an infinite loop.

Does anyone here have other, better ideas about how to assure that the entire process tree is killed when you ^c the Perl script that started it all?

FWIW, I'm working mostly on Windows XP and 2003 Server, but I can't guarantee that these are the only Windows variants these scripts will need to work on.
