That's fine, the problem is that these are now in the buildfarm schedule,
meaning they are no longer in the "get run less often" group.

I've been poking at this further, and it seems like a lot of the problem
is not so much excessive coverage as badly implemented "wait" logic
causing the test to run a lot longer than it needs to.  I already fixed
one such issue in 7834d20b5, and there seem to be more, both in the test
scaffolding and the code-under-test.  Don't know how reasonable it is
to try to fix all this stuff at this point in the development cycle, but
I'm continuing to look into it.
