I'm not too familiar with the internals of the buffer cache, but 'struct buf's can hang around for quite a while in the context of NFS caching, etc, so if you're using jail with NFS, the jail reference might last until the writes are pushed back over NFS (or longer if they remain in the cache due to mmap'ing, etc).
