[Bug 81258] Hardware polling takes over a second with DisplayPort connected

--- Comment #5 from Chris Wilson <chris at chris-wilson.co.uk> ---
Both are issues. At best hardware polling will take ~0.2s (obviously this
scales with the number of attached displays). Almost all software doesn't care
about forcing the detection of new outputs, but only wants to know the current
configuration - the difference is ~0.2s for every single unnecessary call. I am
tempted to make all such queries slow to try and teach application developers
to use the right interfaces.
