For what it's worth, the tests do seem to be in somewhat better shape
on FreeBSD after this change - on my FreeBSD 10 desktop I would
usually see 7 or 8 tests hanging, and now have 3 or 4. It's hard to be
completely certain about the improvement because the failures are not
consistent from one run to the next, though.

I previously saw many more failures on the FreeBSD-CURRENT development
branch, but I haven't yet been able to rerun the tests there.

The most recent timeouts I see are:
