I'm happy for you to check it in. I'll do some further testing in my
branch and see if I can figure out why it isn't working for me.

I've also found the relevant bits in the mips24k programming pdfs
which talk about the Config7 bit which indiciates whether wait will
break if a mask interrupt is asserted or not.
That may be good to include at a later date. (But my SoCs don't have
that feature, so we still need this WAR.)
