OK, I can make the question less vague now.

By chance, another recent question set me thinking about my use of open3().

So I toyed with the code a bit, and found something that makes a difference.

The original code is 

...
    setpgrp(0,0);
    sub killgroup {
        # Make sure all child processes are killed too.
        my $sig = shift;
        local $SIG{$sig} = 'IGNORE'; # don't kill ourselves again
        $Interrupted = 1; 
        kill($sig, -$$);
    };
    local $SIG{INT}  = \&killgroup;
    local $SIG{QUIT} = \&killgroup;
    local $SIG{ABRT} = \&killgroup;
    local $SIG{TERM} = \&killgroup;
    local *CATCHERR = IO::File->new_tmpfile;
    my $pid = open3(gensym, \*CATCHOUT, ">&CATCHERR", "$cmd $args");
...

If I comment out the four lines beginning local $SIG, then it works just like it used to.

Has something changed in Perl since 5.10.1 that would affect this?
