That's the development process I'm targeting when I say cycling tests more
often would be helpful.

The other case is where a developer isn't expecting any change, so isn't
even looking at the latest test results. Automatic email notification might
be very helpful in that case.

That's already being done, and with good success. On my setup, with seven
compilers, it takes close to three hours to do a run from scratch. If there
are just changes to a single library which other libraries don't depend on,
it might take 15 minutes. But if nothing at all changed, it still takes,
say, 14 minutes. It would be nice to reduce that 14 minutes of "overhead",
where some tests are recompiled, even though we know the recompiles will
fail, and some tests are re-executed, even though we know the results of
re-execution. That being said, we don't want to reduce reliability, of
