No, you didn't miss anything.  With the original event patch to the worker
MPM there were separate listener and event threads.  When Paul moved the
patch into the repository as the Event MPM he merged the two threads.  There
didn't seem to be a good reason to revert wait_for_idler back to the worker
behavior at the time.

I will take a look at the bug report and see if I understand the problem.
