Side note - I queried earlier during the discussion about this: how
was this code taken despite having clearly never tested on _anything_?

That's a serious question. Code that simply has never had any testing
AT ALL should not have gotten in.

The use of 'int3' in padding showed the issue, but I don't believe the
code could possibly have worked with the nops and fallthroughs.
