Btw, this double-ssh looks awkward, why not just:

   ssh root_at_tbh.lerctr.org "zfs send ..." | zfs recv ...

or better yet:

   ssh root_at_tbh.lerctr.org "zfs send ..." | mbuffer -m 16M | zfs recv ...

(The misc/mbuffer compensates for bursty zfs reads and writes.
  A note to myself: I should suggest to Allan to add mbuffer
  in a pipe as used in sysutils/zxfer, instead of patching zxfer
  for our local use :)
