SSHKit needs to re-use connections where possible about sshkit

[tilsammans]

Pulled down the memoize-backend branch but that does not fix the issue. After the fifth command still:

cap aborted!
Connection refused - connect(2)

like you would expect.

I love what Mina was trying to do by queueing commands into a single connection.

Not suggesting anyone rewrite the Capistrano command backend, mind you. 😸 But it seems better to pool the (costly) connection as much as possible.

I suggested trying the following to the last person that ran into this: http://www.cyberciti.biz/faq/linux-unix-reuse-openssh-connection/

I'm not sure if Net::SSH is smart enough to do that, but it seems sane to me.

Maybe that's a way to keep this pooling out of SSHKit, and push it down to the layer where I think it belongs.

(I'm not totally surprised that my branch doesn't work, I don't even know if the memoisation is working.

In combination with a .ssh/config in the project directory, that would work for SSHKit.

Inneresting! I am on the go now, but will definitely check that out soon.

Net::SSH doesn't pick that up, regular ssh does though. It's a nice technique, definitely useful. Unfortunately, not for this particular problem.

Thanks for checking Net::SSH, maybe @delano has some idea of of we could
support that in netssh?

I think this can be closed now.
Connection pool is implemented and working.
