Failure point is now chaining, I think.

Ensure that reading the interrupt flags really clears the master bit.
Also makes some guesses on one-shot and reload timing. Alas the test isn't in itself specific enough to be more systematic here.

This is a bit of a guess; it's likely to be true though per the rule that A7 is always kept aligned.
