Detailed Description

Windows implementation of mutex.

Windows mutexes are currently implemented through a Windows CRITICAL_SECTION. For this reason, win95, win98 and winME calls to tryLock() will fail (always return false). Also, as reentracy is not requested by OSTAIL model, rentrant lock ability of CRITICAL_SECTION is a waste of time.

Todo:

Use very low level Interlocked exchange to create a better mutex.
