Some quick debugging shows that the print loop is reached, but that the hash is empty.

return 0 if $pid < 0; wasn't adjusted for the OS.

Windows doesn't support forking. When you call fork a thread is actually created. For those pseudo-processes, $$ is negative, so wait can return a negative number on success.

Use return 0 if $pid == -1; instead.
