As far as i understand not PostgreSQL is using the heap but the system
component user32.dll does. Not sure why user32.dll is needed but i
remember Oracle at least back in 9.x days had the very same problem.

I think i have read somewhere that MS has optimized the Desktop Heap
usage in Vista and later, but not sure where it was.
