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.
