I'd like to turn it on only where it does not cause breakage in either
bootstrapping or testing. Maintaining stability of the testsuite
results, so that we can tell what's a regression and what isn't, is very
useful. Let's at least get it to the point where it's clean on the
primary platforms before turning it on by default.
