Reporting Guide
---------------

If you experience or witness unacceptable behavior — or have any other concerns — please report it by
emailing [******@****.***][codeofconduct_at]. All reports will be handled with
discretion.

In your report please include:

 * Your contact information.
 * Names (real, nicknames, or pseudonyms) of any individuals involved. If there are additional
   witnesses, please include them as well.

 * one or more streams, and then released. An allocated connection won't be stolen by other calls
 * while a redirect or authorization challenge is being handled.
 *
 * When the maximum concurrent streams limit is reduced, some allocations will be rescinded.
 * Attempting to create new streams on these allocations will fail.
 *

 * 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.

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.
