I'm afraid that the above statement means you are not familiar with data race
detection tools. The annotations I added are necessary for every existing data
race detection tool - whether it is DRD, Helgrind or VTune.

As an example, the global variable 'server_start_time' is updated by multiple
threads without protection by a critical section or any other mutual exclusion
primitive. The only way to avoid that data race detection tools complain on
such an access pattern is to add a suppression for that access pattern.
