InhibitHolder increments global counter without using Interlocked. We may want to fix to avoid race conditions that can make this inhibit holder ineffective intermittently and cause hangs.

I did not realize that. This is dangerous and may be already causing some rare failures in stress.

My guess is that this does not complain because DWORD
is typedef, so it is a potentially complex type where the local variable may be impactful ... until some compiler decides to warn for this case too.
I would not hurt to change this one to the make-compiler-happy pattern.
