  while (!_should_terminate) {
    if (CMSIncrementalMode) {
      icms_wait();
      if(CMSWaitDuration >= 0) {
        // Wait until the next synchronous GC, a concurrent full gc
        // request or a timeout, whichever is earlier.

    // Check if we should start a CMS collection cycle

    }
    // .. collection criterion not yet met, let's go back
    // and wait some more
  }
