It should actually be a bugcheck with THREAD_TERMINATE_HELD_MUTEX, but I 
only discovered this weird Bugcode much later after coding this. See 
some information here:

http://groups-beta.google.com/group/comp.os.ms-windows.nt.misc/browse_frm/t…

here:

/
// MessageId: *THREAD_TERMINATE_HELD_MUTEX*
//
// MessageText:
//
//  A kernel thread terminated while holding a mutex
