  // with the repository and (2) load a DLL and hence lock the

  //
  // Now if we don't lock the repo here, it is possible that two
  // threads may deadlock on initialization because they can acquire
  // locks (1) and (2) in different order, for instance:
  //
  // T1: loads a DLL (2) and registers a service (1);
  //
  // T2: may be relocating a service (1), which could lead to a
  // (re)opening or uping the ref count on a DLL (2);
  //
  // To prevent this, we lock the repo here, using the repo_monitor_
  // member guard.
