Btw, this double-ssh looks awkward, why not just:
ssh r...@tbh.lerctr.org "zfs send ..." | zfs recv ...
or better yet:
ssh r...@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 :)
