First - let me say I TOTALLY agree with your concept for more
async features and design!!!

Second - there is no way that disconnected/async events that can
jump threads will ever fit into httpd-2.  That quantum leap must
be httpd-3 because it breaks the assumptions and gross hacks of
many module authors.  Even if we 1. never leap threads between
translate_name and finalize_request, therefore 2. restrict all
async to the reception of the request packet; there will still be
affected modules, mod_sspi and user tracking apps that span
pipelines - which don't expect data to jump threads on the connection
layer.

Absolute rule, trunk/ should always build as well.  If it can't build,
it should be reparable within a very short window.  Hopefully not by
the committer, but more likely, by platform maintainers 'catching up'.

That said, I'm strongly -1 on dropping such radical changes directly
into trunk/.  There is no way code changes on this scale are ever CTR.
We have SVN, so creating sandboxes/experimental/proof-of-concept
branches are trivial :)

This was true of every major refactoring of Apache since Shambala.
Create a sandbox today to start experimenting with async models.

So to amend your original proposal; on May 13;

  * tagging an alpha candidate
  * identifying all showstoppers to GA

and if that list is short enough, we will be able to read how long
the window from 2.1-dev to 2.2 GA actually is, and if we are fitting
into something that resembles a one month timeframe.
