#### Do-stuff-later pool

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

 * data.
 *
 * Many methods in this API are **synchronous:** the call is completed before the method returns.
 * This is typical for Java but atypical for HTTP/2. This is motivated by exception transparency:
 * an [IOException] that was triggered by a certain caller can be caught and handled by that caller.
