On some operating systems sched_yield is a stub. usleep should at least trigger a context switch if any thread is waiting. A ThreadYield() would be nice in winpr ...

The LockCount field indicates the number of times that any thread has called the EnterCriticalSection routine for this critical section, minus one. This field starts at -1 for an unlocked critical section. Each call of EnterCriticalSection increments this value; each call of LeaveCriticalSection decrements it.
The RecursionCount field indicates the number of times that the owning thread has called EnterCriticalSection for this critical section.
