Issue diagnosed and reported by Ambroz Bizjak. The dbContextReadNotifyCacheAllocator allocator clears its cache of free buffers on an array size change. But doesn't consider buffer already in use, which will later be free'd. Such buffers were being returned to the cache, then reused in allocations for which they are too short. Track the size of buffers which are in use. Only return buffers with the present length to the cache. Others are free'd immediately.
