nsmux can shutdown all dynamic translators on exit
Now nsmux can shutdown all of its dynamic translators on exit, thus
doing sufficient cleanup. One can tell nsmux to shutdown dynamic
translators using the ``--recursive'' option to settrans. Note that
because fsys_goaway returns immediately as the RPC is processed, while
the receiver may still remain in memory, doing something like
settrans -g --recursive foo
where nsmux is sitting on foo will almost always result in a ``Server
busy'' error message. The reason is that libnetfs counts how many open
ports to its nodes there are at shutdown and in most cases it does the
check *before* the dynamic translators manage to drop their
references. Therefore, the aforementioned command gracefully kills all
dynamic translators. Invoked the second time, this command will
shutdown nsmux, too. Immediate shutdown with killing dynamic
translators can be achieved via
settrans -gf --recursive foo
