The bucket allocator cleanup problem might have been a contributing  
Here's the patch I checked in to the trunk late yesterday:

The async write logic may have increased the probability of buckets
remaining in brigades in the connection pool after the last request has
been processed on that connection (e.g., if a client drops the  
before the response is completely sent).  That would be enough to
trigger the "freeing buckets allocated from an allocator that has
already been destroyed" situation.
