public int getMinimum() {
    return minimum;
  }
Responsible for counting connections.
The count maintained by this class will eventually be consistent with the actual number of
connections. Since the count is changed before and after the actual connections are created and
destroyed, and not changed while holding a lock, the count should be treated as an estimate of
the current number of connections.
