That is a valid concern.  Unfortunately, I do not have an answer to
that, as I have not dug into the apache code itself.  I apologize that I
cannot contribute to an answer in this particular case.

Your buckets can still be created using the request->pool .  My created
buckets in my output filter are done that way.  Have you tried it?  You
still use the request->connection->bucket_alloc for the other parameter,
but the request->pool for the memory pool to be used.
