Looking at t0027, it turns out that the changes in the test matrix done in 1/2
are reverted in 2/2.
This is not a good thing.
Either (a) they should be marked as test_expect_failure in 1/2 and
corrected in 2/2,
or (b) 1/2 and 2/2 are squashed together and the noise in t0027 is minimal.
Probably (a) is a bit more kosher and useful when somebody wants to
inspect the history of the test ("the test was flaky and that hid a
few bugs, but we fix the timing-dependency which exposes the bugs"
in 1/2, "this is the fix for the bug that the previous one exposed"
in 2/2). (b) might be a bit less work, though.
