Hmm, but how? One of the things we gave up by nuking HPPA support
was that that platform's representation of an initialized, free
spinlock was not all-zeroes, so that it'd catch this type of problem.
I think all the remaining platforms do use zeroes, so it's hard to
see how anything short of valgrind would be likely to catch it.
