If a CRITICAL_SECTION is not initialized with a spin count, it will default to 0, even on multi-processor systems. MSDN suggests using 4000. On single-processor systems, the spin count parameter is ignored and the critical section's spin count defaults to 0. For Windows >= Vista, extra debug info is allocated for CRITICAL_SECTIONs but not released in a timely manner. Consider using InitializeCriticalSectionEx(CRITICAL_SECTION_NO_DEBUG_INFO).
