Comment:

 This is a known issue, which have no general solution.

 The problem is that multiple threads may try to update the counters at the
 same time and if they race, updates may get lost.

 We try to minimize cases where this happens by updating counters under
 appropriate locks, but this is not always feasible.

 In the few remaining cases, the overhead and contention on a dedicated
 lock for the counters would be significant.
