Revisiting this topic from a looong time ago...

Did you ever get a chance to do any further work on this
design?  IMHO, for 2.1/2.2 we should at least incorporate
the changes to allow data to be pushed rather than pulled
through the input filter chain.  That will set the foundation
for an event-driven MPM, even if we're still using a blocking,
thread-per-connection worker design in the first 2.2 release.
