Threading* tests are a summary of essentially normal tests that are defined
using the THREADED_TEST macro instead of TEST. So we already have
single-threaded coverage on those tests, but run them multi-threaded again. In
order to reduce runtime, Threading tests are divided into four parts. It just
happens that parts 2 and 3 are somewhat faster, but it seems arbitrary to me to
mark only 1 and 4 as slow.

Imo we can remove all 4 parts.

Or divide them into more parts, but that probably wouldn't make the total run
time any faster.
