this bug is caused by Windows API "CreateToolhelpSnapshot", and cannot be fixed 
unless I use alternative ways to enumerate processes.

So you have left it unfixed and you're satisfied with making people waste lots of resources.

Page Faults

I think you should seriously re-think process enumeration and you should not poll the entire process list periodically but asynchronously hook to the Windows API and detect when a process is launched. I'm sure it's possible.

This amount of page faults is simply unacceptable.
