Specify the spin count for FairCom DB critical sections on Windows. Only Windows versions supporting the CriticalSectionAndSpinCount() function (0x403 or greater) have this feature enabled.

This configuration option includes Unix/Linux systems. The default value is 1000, meaning that we try up to 1000 calls to pthread_mutex_trylock() before making the blocking pthread_mutex_lock() call.

Default: 1000
