allow the reactor to remain running after a Commando job finishes

I tested this out and it seems to work fine. The only thing I noticed is now there are messages like this in debug/verbose mode:

    2013-10-28 11:40:09-0400 [ops-switch01.nyc02.foo.net] Timed out while sending commands
    2013-10-28 11:40:09-0400 [ops-switch01.nyc02.foo.net] Forcefully closing transport connection
    2013-10-28 11:40:09-0400 Got disconnect request, reason: 10, desc: 'user closed connection'
    2013-10-28 11:40:09-0400 Disconnecting with error, code 10
            reason: user closed connection
