Also it's somewhat useful if using a separate tunnel process (openssh
for one can do this now).

Acked-by: Richard W.M. Jones <rjones@redhat.com>

If we could have the same change on the qemu client side that would

https://github.com/libguestfs/nbdkit/blob/e0d324683c86455a2fe62e97d57f1313cad9c9f3/tests/functions.sh.in#L133
