## Risk Assessment

### Technical Risks
1. **RDMA Complexity**: Limited Java RDMA support may require JNI
2. **Multi-Channel Synchronization**: Complex thread synchronization required
3. **Persistent Handle State**: Requires reliable state persistence mechanism

     *
     * - Any kind of Error from a listener. Even if we could distinguish that case (by exposing some
     * extra state from AbstractFuture), our options are limited: A call to setException() would be
     * a no-op. We could log, but if that's what we really want, we should modify
     * AbstractFuture.executeListener to do so, since that method would have the ability to continue

   * and response body streams; otherwise resources may be leaked.
   *
   * This method is safe to be called concurrently, but provides limited guarantees. If a transport
   * layer connection has been established (such as a HTTP/2 stream) that is terminated. Otherwise,
   * if a socket connection is being established, that is terminated.
   */

         *
         * Ideally we'd have a real eviction policy, but until we see a problem in practice, I hope
         * that this will suffice. I have not even benchmarked with different size limits.
