OpenVMS crash

[Steve Reece_3]

Just because CIFS is running in user mode doesn't mean that everything else around it and everything that it's affecting are in User mode.
If the system takes out a lock that then gets corrupt due to imperfections elsewhere, that can still cause a crash. This is analogous to a double deallocation of memory that would still cause a crash even though the deallocators may be millions of clock cycles apart.

Looking at the whole problem rather than the little bit of it may be necessary.
