--------------------------------------------------------

Ran tests overnight, no looping detected. Put
{noformat}
    while (backingStore.putIfAbsent(blockName, scache) != null) {
      int i = 0;
      Thread.yield();
      i++;
      if (i > 1000){
        System.out.println("TEST FAILING AT REMOVE");
      }
    }
{noformat}
in the two while loops.

Will put out patch v3 in a moment.
