You have stumbled upon some Unix lore here. The problem is the stdin
file descriptor, as ssh will not return if stdin is still open. A
simple solution is to run lamboot with something like "lamboot -v <
/dev/null" so that stdin is closed from the start. In the future, we
might close stdin internally, but there are some legacy reasons that
the code is the way it is.
Hope this helps,
