Try out this sample code ( should work on Linux - be careful before trying on Solaris ) : 
use strict;
my $pid = $$;
print "My PID is $pid\n";
fork and exit;
sleep 1 while -e "/proc/$pid/cwd";
print "My PPID is ", getppid, " after my parent is killed\n";

It would return original parent's id that forked the child and pid of current parent. Any idea how to work around this problem ?

Thanks,
