Didn't even know about it.  I looked at the Illumos commit log and
figured out that I should be able to work around it by setting
checksum=fletcher4.  Since it's a production server I can't really
take a reboot just to try this out.  (I added it to loader.conf just
now, so if I need to reboot it again before this bug is fixed, I can
put it back to sha256.)
