URL: https://github.com/apache/geode-native/pull/594
Re-implement FairQueue as ConnectionQueue.
* Use std::mutex.
* Use std::recursive_mutex.
* Adds unit test
Benchmark Summary:
New implementation is on par with ACE version where non-recursive mutex is
used. New implementation is faster where recursive mutex is used.
Benchmark Results:
Run on (12 X 2900 MHz CPU s)
CPU Caches:
