Sometimes there's an action required like calling the application layer or responding to a ping, and the thread discovering the action is not the thread that should do the work. We enqueue a runnable on this executor and it gets handled by one of the executor's threads.

### Locks

We have 3 different things that we synchronize on.

#### Http2Connection

    async calls to this new API, `Call` is now the first parameter for both
    `onResponse()` and `onFailure()`.
 *  Fix: handle multiple cookies in `JavaNetCookieJar` on Android.
 *  Fix: improve the default HTTP message in MockWebServer responses.
 *  Fix: don't leak file handles when a conditional GET throws.
 *  Fix: Use charset specified by the request body content type in OkHttp's
    logging interceptor.
