Comment (by aaugustin):

 I tried writing a test for this but it's hard. The following test fails
 when the bug is present and hangs when it's fixed:

 TestserverCommand

 }}}

 I don't want to make a test that depends on a `time.sleep(2)` because it
 will be slow and flaky. I don't have a suitable way to detect that
 `runserver` has forked a child and is running. I can't run `runserver`
 without autoreload because that makes the bug go away.
