that makes sense to me too for my own purposes, but

1) before long I suspect some folks will want/need a single shared
   library version of APR which works with multiple APR apps

   and it won't just be "want" because they think it will be nicer to
   have one build of APR... it will be "need" because different
   dynamically-loaded code will have to use the same copy of APR*

   (*maybe gstein could chime in here... some months back there was a
   discussion of why single shared library of APR was so important)

2) even if, back to the Apache example, we use the prefork MPM, we may
   have a module which uses threads; I've been told there are threaded
   modules for Apache 1.3...; presumably we'd want such modules to
   work with APR with Apache 2.0

I'm a bit surprised that none of the folks who were around when
CROSS_PROCESS vs. LOCKALL was invented have participated in the
discussion.  I think I'm at least as concerned with that as with
losing a lock flavor.
