I've managed to write a timer that reliably causes keyboard input not to be accepted until I press
The issue is, I don't know what causes the timer to lock up, what the stack frame is when it's locked up, or how to unlock it.
(signal 'quit)resolves the issue but this isn't a reasonable fix.
- Using gdb doesn't point to a function which is blocking input.
toggle-debug-on-quitdoesn't give a useful stack trace.
In Python I can press Ctrl-C to get a stack trace of the code being executed. Why doesn't Emacs let me interrupt my timer's code with
