Queue overflow can lose state #8
Description
It's possible for the event queue to fill up during long pauses in running the scheduler, such as while playing the Mastermind game. This can cause important events, such as the event that saves a score update to the SD card, to be lost silently.
Really, there shouldn't ever be any long pauses of the scheduler, but that will require re-architecting Mastermind, at least.
It's unknown whether this explains the phenomenon of CHIP8 game scores going unsaved, but it sure might.
