This is a race, which the second ssh connection loses: the socket
doesn't exist when it checks to decide whether is need to become
a ControlMaster, but then the socket has appeared by the time it is
trying to become one.

Either, this needs to be handled differently, or ssh should try to
use the existing socket, even though it previously decided to become
a ControlMaster.

The warning is now

ControlSocket
/home/madduck/.var/ssh/ssh_control_piper_seamus_22_madduck already
exists, disabling multiplexing

but the connection works. It would be nice to disable the warning
still...
