In the interpret() loop, input events are handled by bytecodes (see 
primitiveKbdNext, primitiveKbdPeek, primitiveMouseButtons, 
primitiveInputSemaphore, primitiveGetNextEvent, primitiveInputWord).

When primitiveQuit bytecode is encountered, VM terminates itself by calling 
exit functions in the display module (see ioExit()).

It starts interpreting bytecodes from last snapshot point. See 
primitiveSnapshot().
