[erlang-bugs] ^G-q in remote shell quits erlang node

[Johannes Weißl]

A short update:

I ran "erl -remsh" in a screen session, maybe this has something to do
with "^G-q" being transmitted to the production node.

To mitigate the problem, I start the production node now with "+Bi" so
that "^G-q" is forbidden there.
