     *   increase availability of multi-homed services.

   * value. Note that multiple threads can concurrently load values for distinct keys.

 *  Fix: Don't release HTTP/2 connections that have multiple canceled calls. We had a bug where
    canceling calls would cause the shared HTTP/2 connection to be unnecessarily released. This
    harmed connection reuse.
