  Log:
  Fix a race condition in mux_fini() where we were checking the "closed"
  flag without holding the multiplexer lock, so it was possible to have
  two threads racing for the shutdown.  Fix this by calling mux_shutdown()
  unconditionally in mux_fini() and by checking the closed flag in
  mux_shutdown() when we hold the multiplexer lock.
