Description Salvador Fandiño 2012-02-23 03:30:34 AEDT 
When ssh is run in master mode and with the -N flag, it should terminate after receiving the "stop" control once all the slaves (and port forwarders?) are done.

tell mux master to close when using -N and all clients gone

ok, so the problem here is that ssh assumes there's still a session in this case, then eventually runs a select(2) that never returns.

the attached patch should fix this, please try it.
