Disabling interrupts doesn't stop the flag being set, it just stops the 
interruption points acting on it. There is thus no need to clear the 
flag. If you want to call code with an interruption point without being 
interrupted, disable interruptions. Whether or not the flag is set 
beforehand, or set during the call is now irrelevant. It may or may not 
be set at the end of the block either way.
