Well, if it helps, I've significantly overhauled the code for Win32 to
allow 'try'
semantics on Win32, which returned ENOTIMPL before. Possible this is
part of your headache.

We will now have a mutex object on 9x, a critical section on NT, unless we
explicitly request an APR_THREAD_MUTEX_UNNESTED flag to _create().
In that case, I've written an event-based model that's guaranteed to deadlock
on the same thread... maybe these issues are part of the problem you observed?
