I am not sure why I would want to support the workflow this is
trying to help.
I do not want to see a patch on this list claiming that "While the
whole test suite is running, I tweaked the source three times and
recompiled, so some tests may have used my second iteration while
others may have used my third and the final version of the code---in
any case, all tests passed". And when a patch that was developed
that way came in, I do not want to hear "Yes, the test suite used
mixed binaries, but I KNOW the difference between my second and
third iteration should not matter the parts of the earlier tests
that used the older iteration".
