No, this is not the purpose of the changes. The primary purpose of the redesign
is to allow the mpms (threaded in particular) to work in some semblance of a
reasonable fashion when max_requests_per_child is set to anything other than 0.
This includes both cleanup related issues and overall throughput. Right now, the
threaded mpm performance sucks if mrpc is set to anything other than 0 (or some
really large number) and you can't set it too big because of memory leaks.

Any other benefits gained by the redesign are side benefits. They are nice,
but not a reason to justify (or veto) the basic ideas.
