Comment (by warner):

 The branch is ready to land. It looks like there's one `deferToThread`
 left in the test suite: `test_runner.RunBinTahoeMixin.run_bintahoe` uses
 `subprocess.Popen` underneath `deferToThread`. I *think* this can be
 replaced with a `reactor.spawnProcess`, but I'm not 100% sure, and I don't
 want to go messing with it right now, so I'm going to leave that cleanup
 for another day.
