Fix cache - hurley

Results from the past week
  • Some discussion w/in networking team about using finer-grained locks (bug 723577) vs. just moving everything that touches the cache off the main thread (bug 722034). Work has been done on both approaches. Bug 723577 is in second round of review (pending decision on this discussion) and is considered more dangerous; bug 722034 has had no reviewable patches, but the approach is considered less dangerous.
