Patch submitted to qpid-dev by ksmith@redhat.com. Fixes concurrency issues arising from previous move to use singleton apr pool.
"My patch does three things:
1) Modifies the APRPool class to use alloc/free semantics for APR memory pools. Each time a caller calls APRPool::get() they'll their own pool reference. I've fixed up all the call sites I can find to also call APRPool::free() at the appropriate time.
2) Caches freed APR memory pools in a STL stack. This cuts down on the number of memory pools created overall.
3) As a result of doing #1 and #2 I've introduced a guard mutex around APRPool::get() and APRPool::free(). This is to prevent concurrent access to the memory pool cache. If it's too heavyweight, the mutex along with the caching mechanism could be removed entirely."
