The current SS uses the global mutex to synchronize access to the shared
data structures between all running threads. Given the fact that almost
every operation requires at least read-only access to these shared
structures, it's easy to understand that only one thread will be active per
moment whilst others will be locked (i.e. waiting for the mutex to be
released).
