Remote SSH hangs

There is an SSH pathology on some connections (perhaps remote firewall related?) that causes the frequent ssh connections used by this script to hang sometimes and the transfer to fail.

Workaround?

Use the ControlMaster setting in ~/.ssh/config (e.g. as documented in http://www.anchor.com.au/blog/2010/02/ssh-controlmaster-the-good-the-bad-the-ugly/) and the hangs disappear.

Highly recommended.
