Urgent: Can't get REPL to work anymore (for a live demo!)

[Robert Field]

Yep, from the failure it looks likely to be related to socket or memory 
issues, so I asked him to try a reboot while I dive deeper.

What is null is the output stream that gets set during opening the 
socket.  But if that fails it should throw an internal error and die, 
looking...
