This probably needs fixing for all the non-webview usage as well, even though I don't think those callers use setHandler, because the default handler is the UI thread anyway and so the callers that don't call it are also broken.

This wants to be merged to M71 so we can test it doesn't break things in beta.

I'm going to do the merges etc. This should be fixed on 72 now.

Per the internal bug, the CTS test failure is hard to repro (we're not sure what the preconditions are for it to fail) so this may be hard to verify; the plan is to merge the fix to 71 and look at the results after 71 is dropped into internal master.

This bug requires manual review: M71 has already been promoted to the beta branch, so this requires manual review

Torne, did you merge http://crrev/i/701668? I can't find the downstream release branch.

Whoops, no I didn't. I'll do it now.

vakh@ may be interested in this. This is specific to connection-based APIs, but connectionless APIs may have similar gotchas.

Please add QA Manual verificato0n steps to be verified on M71
