We have a dead-lock between the RmapListLock and a address space lock. If a 
page fault is handled, we have locked the address space and calling 
MmInsertRmap, which tries to get the RmapListLock. A second thread does 
currently page-out a page. It calls MmDeleteAllRmaps. The RmapListLock is held 
by this thread. MmDeleteAllRmaps does call MmPageOutDeleteMapping for all 
mappings. MmPageOutDeleteMapping tries to lock the address space from the 
first thread.
