that's still my favorite if we can swing it.

I don't think we can really do that with APR.  once the APR interface is
capable of being separated it makes little sense to have things in the MP::
or any other mod_perl related namespace.

not really.  can you explain exactly what the issue is with $!?  I never
quite understood why it wouldn't work and today I was playing with
BerkeleyDB and saw that it relies on $! to communicate errors.  I could have
sworn that a few other modules used its dual-value nature as well, but I
could be wrong.
