Best guess is that we corrupted a bucket brigade by double freeing it, or something of that kind. This is definitely a new behavior since the async-write code was merged into trunk. It is odd that we could of double-free'ed something on the connection pool. Maybe it isn't a double-free issue at all...
My other thought comes down to the thread locking. Perhaps we are looking at an issue of two threads touching the per-thread non-locking allocator at once? The reason I suspect is that it -seems- your process ended up with a linked block list with a cyclic loop.
