Patch submitted to qpid-dev by [EMAIL PROTECTED] 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."
