Attaching a shell to a running node.

[Logan, Martin]

You can start multiple remote shells and juggle sessions that way (just
make
sure you pay attention to what node you are on before running arbitrary
commands :-)

One in particular to watch out for is doing q() when in a remote shell
session.  This will not stop your local shell but, as I found out the
hard way on a production node, will bring down the remote node :-O
