remove the commented-out line?

eek, who sets $restore_dir?  Oh, sourcing common/dump does.
But nothing mounts $SCRATCH_DEV yet, right?  So this seems
like a combination of incorrect, unnecessary & dangerous.
(_wipe_fs will re-mkfs anyway).  I'd just remove it.

$tmp is /tmp/<our pid>

so /tmp/<our pid>.stream *really* shouldn't exist, and cleanup
should have removed it from the last run (with a different pid).

But I suppose it doesn't hurt to be sure...

Ok, wipe_fs does mkfs & mount.  Could you add a comment?

> +mkdir $dump_dir 2>&1 >> $seqres.full || _fail "mkdir \"$dump_dir\" failed"

same deal w/ the order of the redirects.  More below too.

Otherwise looks ok.
