The loop it's called in is not processed bazillion times per second
(though it *is* called surprisingly often; small, fast jobs can result
in somewhere in the order of magnitude of 100 iterations per second on
a fast CPU). As you said - I expect it's negligable compared to fork()
and the work jobs themselves do.
