+1 for concept, didn't review your divisions.

Something related I've been wondering about is whether we could
parallelize the isolation tests.  A difficulty here is that the
slowest ones tend to also be timing-sensitive, such that running
them in parallel would increase the risk of failure.  But we
could likely get at least some improvement.
