Before, it would max out a cpu core at 100% while waiting (undesirable if what it's waiting on needs the full cpu). Adding a 1ms sleep reduced its usage to about 1% in my case.

Changing WNOHANG to 0 was the first thing I tried, but it was returning prematurely (which seems to contradict the waitpid documentation), so I went with the sleep instead. |
