## Risk Assessment

### Technical Risks
1. **RDMA Complexity**: Limited Java RDMA support may require JNI
2. **Multi-Channel Synchronization**: Complex thread synchronization required

   * Our usages should at least be *relatively* safe: Typically, threads started by a test are dying
   * at the end of the test, so there is no object state put at risk by stopping the threads
   * abruptly. In other cases, a test may put a thread into an uninterruptible operation
   * intentionally, so there is no other way to clean up these threads. (The better solution,

   * risk exhausting memory.)

- Fix component status calling etcd health endpoint over http which exposed kubernetes to the risk of complete watch starvation and is inconsistent with other etcd probing done by kube-apiserver.
