There are a number of tests that are skipped due to SLOW=no on "review" builds, but only take a minute or so. Some only take a few seconds. Enabling them would improve test coverage, and only increase testing times by a small fraction (10 minutes over a normal 7h test run).

All of the tests that will be enabled are currently passing on master for at least the past two weeks.

There are still some tests that take tens of minutes to run for "full" test runs that will continue to be skipped for "review".
