If I replace the two signal handler calls in src/main.py with:
old_handler_int = signal.signal(signal.SIGINT,
signal.default_int_handler)
old_handler_term = signal.signal(signal.SIGTERM,
signal.default_int_handler)
It makes no difference, freevo sometime does and sometimes doesn't shut
down. I assume that signal.default_int_handler is the kaa handler.
Once I saw this:
DJW:Starting kaa main run loop
Shutdown by keyboard interrupt
DJW:shutdown(menuw=None, argshutdown=None, argrestart=None, exit=False)
This seems to work until a key has been pressed and then it blocks.
We need the SIGTERM handler too as DirectFB calls this from the SIGINT
handler.
