the first known flake is 2017-05-15 16:57:42 UTC

It looks like all we need to do to fix this is make SpeechRecognizer a base::RefCountedThreadSafe<SpeechRecognizer, BrowserThread::DeleteOnIOThread> instead of just a base::RefCountedThreadSafe<SpeechRecognizer>.  Do we really care so little about speech recognition integration tests that no one has looked into this apparently fairly simple fix for the last four months?

Sorry - that should have been phrased a bit more politely, just a bit surprised to see of the only two browser_tests for speech recognition, one is disabled everywhere (And was apparently never looked into), and the other is disabled on OSX, and no one looked into that, either.

mmenke@ - if you could upload a patch for review, that would be a huge help for us. Thanks!
