I don't think they ever did :-(. The theory is good, but useful values
for commit_delay would probably be under a millisecond, and there isn't
any portable way to sleep for such short periods. We've been leaving
them there just in case somebody can find a use for 'em, but I wouldn't
object to taking them out.
