minutes (i.e., ~45 times now). While its determination is laudable, I think
it could stop after maybe 3.

It used to only try 3. I'm not sure why it's looping forever now. I also can't investigate until Monday or Tuesday, and GCE changes broke Plan 9 anyway, so I just disabled Plan 9 builders for now.

CC @golang/release.

Fixing this for the rest of the builders involves starting to track the number of retries (for a high-level trybot request on a given repo/commit) due to communication errors, and modifying repeatedCommunicationError to return a non-nil error if that number reaches 3. It's currently a TODO comment in that method:

// TODO: give it two tries at least later (store state
// somewhere; global map?). But for now we're going to
// only give it one try.
