I'm not sure fork is the right tool here. I recently came across an easy to use module to put things in the background, Proc::Background that may help (cross-platform even).
use warnings;
use strict;
use Proc::Background;
my @cmd = qw(perl sleep.pl);
my $proc = Proc::Background->new(@cmd);
my $pid = $proc->pid;
print "*** $pid ***\n";
Output showing parent exits while proc still running:
~/scratch$ perl proc.pl
*** 3489 ***
~/scratch$ ps ax | grep sleep
3489 pts/1 S 0:00 perl sleep.pl
