This test has been the primary source of test suite unreliability in recent weeks. By marking it "slow" I'm effectively disabling it on CircleCI, which I think is acceptable because (1) it is, in fact, quite slow; (2) it passes locally on Linux; and (3) it depends on the timing of file change notifications, which is a recipe for test flakiness due to the general non-determinism of file watching, but not necessarily a sign of a broken developer experience. Like other "slow" tests, I will keep running this test locally via meteor self-test --slow 'javascript hot code push' as part of the manual QA testing that we do.
