23+-- Notice to those working on this test suite:
24+-- It doesn't appear to be possible to use --match to run a particular test, in
25+-- this situation the test may hang before reaching our code. This seems to
26+-- happen when the test is not the first test in the block. As a workaround, you
27+-- can just comment out the other tests. Also, using `xit` will cause the same
28+-- issue. `xit` tests must be the last tests in the session, or the session will
29+-- hang in the following test.
