looks like a global variable is exactly what your problem is.  somebody is
creating an Apache::SubRequest object (via $r->lookup_{file,uri}, and it's
not going out of scope until the child exits.  in this case, when
Apache::SubRequest::DESTROY is called, it calls destroy_sub_req() on a
pool that's already been cleared.
