Comment (by teor):

 I think the 0.2.9 issue might be caused by timing differences between
 0.2.9 and 0.3.4 and later. (In 0.3.3, we changed many events in the  event
 loop from "once per second" to "as often as possible".)

 Here's what I'd like to try to fix this issue:
 1. Fix #22132 and #28203, so that we start testing once 0.2.9 has
 bootstrapped
 2. Disable (parts of) the change in b0e98fcc for 0.2.9
   * "Fix a common Travis failure mode by allowing tor more time to
 bootstrap. And double the consensus interval."
 3. Implement #29729, #28204, and #28220 to find out how bad the problem
 is, and where it's happening
 4. Work out how to get a copy of the whole chutney directory so we can
 check the logs
