PageFaultFatal
Debugger Support Under Virtual Memory
A debugger can use the PageFaultFatal function to determine whether it should capture all bus errors or whether it is safe to allow them to flow
through to virtual memory. When paging is safe, the debugger can allow
virtual memory to continue to service page faults, thus allowing the user to
view all of memory.
Notes: If this function returns TRUE, then the debugger should not allow the
virtual memory's bus error handler to detect any page faults.
