Yes, this doesn't sound good. I sort of like the way it already exists,
i.e., that the GUI interprets the SIGINT based upon what window is
active, and if it is the terminal window that is active issue an
interrupt back to the OS with the target being the Octave-core thread
which the GUI knows because it is the one that launched the Octave-core
thread and should have a record of process information.

My understanding is that signals are per-process, not per-thread, so there is no way to direct the signal to a specific thread. If there were, then the solution would just be to direct the signal to the correct thread. But I don't see any way to do that.
