I agree that the overeager has the worse worst-case bound. I'll happily approve
a patch that drops overeager and leave double-queuing only, provided we have
empirical data over some known programs to show that it is a compile time
neutral change (I bet it will be so, or worst case, only a very slight
slowdown).
