Windows: uses Mutex, the handle can't be shared among processes, but the mutex still can be be shared by passing a common object name to createByName() / <a class="el" href="classNLMISC_1_1CSharedMutex.html#a1">createByKey</a>().
<p>
Note: the mutex must be explicitely destroyed by calling <a class="el" href="classNLMISC_1_1CSharedMutex.html#a2">destroy</a>().
