Also, is there a way I can trigger the auto tester to run a few more times
w/o committing anything?  Everything passed on the latest run except
Windows, which is broken for unrelated reasons, but I want to see whether
I've solved the problem or the issue is non-deterministic and I just got
lucky.  (On FreeBSD everything started working after a change that shouldn't
have mattered, but my gut feeling is that the failure here was due to a
codegen bug.)
