... but doesn't perform as expected in the Windows world.

That's a pretty poor description of the problem. What are you expecting and how does what you are seeing differ from that?

The non-blocking form of waitpid seems to work fine on my system: 

use POSIX qw[ :sys_wait_h ];;
$pid = open O, '| perl.exe -e"sleep 10; exit(123)"' or die $!;;
print waitpid( $pid, &WNOHANG ) while sleep 1;;

So how is it "not performing as expected" for you?

Also, showing the open being used woudl be a good idea as that can influence things.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
