Thread rundown -- [was ExReleaseResourceLite]

Actually I would like to know if any rundown processing is performed on resource
objects owned by a thread at thread termination time , and if there is a provision for
bugchecking the system in the case of any of them is acquired. From tracing
in Windbg it seems to me that such a rundown (with respect to synch objects only )is
only performed for mutant objects.
