[Twisted-Python] Retry: Conch Issues

I am having troubles with Conch. I've been able to reproduce them in a unit test and all the code is here along with requirements.txt: https://github.com/radifalco/conch_issues I'm trying to reuse my connection, but if it is idle too long the server shuts it down. What I don't understand is why the next call to `FileTransferClient` does not call back or errback? It will just hang forever even though the Factory and Transport know the connection was closed (as evidenced by the log messages). I don't ever want to hang, if I use FileTransferClient I would like it always call a callback or errback. I feel like Conch is missing a deferred somewhere but damned if I can find it. Thanks!
