Acquiring reader lock, the upgrading it to writer lock then again acquiring
reader lock and upgrading it to a writer lock (recursively) causes
ReleaseReaderLock to throw "ApplicationException: The thread does not have any
reader or writer locks". This doesn't happen on .NET. This behavious is
observed both on mono 2.0.1 and 2.2

Reproducible: Always
