I assume the real issue here is that CreateProcess is being called with 
bInheritHandles set to TRUE, I think we might have to dig into the 
reasons for that as I'm sure it has been looked at many times. There is 
also code in the Process implementation to toggle the inheritance 
setting prior to calling CreateProcess and I'm also curious why that 
isn't working.

So while you proposed change is benign, I think there may be more going 
on here that we should look into.
