Camble's Safe shutdown vs mholgatem's GPIOnext

[boquetipo]

Hi,

I've been having problems between these two scripts/jobs/tasks when they are running at the same time.
Separately they work like a charm.

Every time I moved the switch (to 'ON' or to 'OFF'), the rpi0 seemed to shutdown, but out of the blue started running again (like a reboot).
So I had to change to Adafruit's retrogame in order to get buttons work through GPIO.

Does anyone had this very problem?

Thanks.
