Follow-up Comment #8, bug #37795 (project octave):

Note that even QtHandles won't be fully functional without the readline event
loop. The fact is that the readline event loop is used as a way to feed
something to octave to be executed synchronously. In the case of QtHandles, it
would be the callbacks.

Using the readline event loop for this kind of purpose is probably not a good
idea, but that was the only solution at the time. With the GUI development,
there have been other mechanisms added to allow to communicate with octave. I
didn't look into it in details, but it might be wise to move the
octave/toolkit communication outside of the readline event loop.
