Hmmm... notice that APR_HAS_THREADS is irrelevant to the MPM selected... you
_can_ using threading support in APR with a prefork MPM, and there may be
modules that need just that configuration someday soon (say, child threads
in a mod_proxy or servlet environment).
So you can't indiscriminantly disable APR threads 'just because', there is
going to need to be a bit more logic. Contrawise, just because the user
enables APR threads does _not_ mean they are choosing pthreads ;-)
