Something in r291926 (and earlier) causes reboots during periodic daily (14 jails on system)

I doubt very much that's involved; I have multiple production systems with dynamic_write_buffer turned on and I've yet to see a panic from periodic activity or anything like it. The only panic I've got open right now that's related to ZFS happens during a send/receive backup and it's able to be reproduced only with difficulty (it looks to be a problem in snapshot management as I've isolated it fairly well but haven't yet found the root cause) -- and it can be coaxed out of a bare "clean" -STABLE install with no ZFS patches in at all. (The codepath that results in the panic doesn't have a logical connection to that patch, but I tested without it anyway just to make sure.)
