See:
http://msdn.microsoft.com/library/de...LockTopic1.asp
You can call AcquireReaderLock multiple times aka "recursively" ergo you
need to call ReleaseReaderLock the same number of times, the same with
WriterLock.
Each time you call AcquireReaderLock the lock count is incremented by one,
each time you call ReleaseReaderLock the lock counted is decremented by one.
