There is a protocol stream. If the app is putting commands into
the stream and a signal interrupts it and the single handler puts
commands into the stream, this is an error. You cannot do this.
If you really need to draw something from the signal handler
you should use a separate display connection to do that so that
it doesn't trash the other one.
