In this case a particular narrow aspect of performance was testable in
way that can be executed as part of the automatic suite.

I can find only one directly timing related case,
LayoutTests/fast/forms/slow-click.html (thought <video> tests in
branch have a ton more). I suspect number of others are timing
dependent indirectly.

It does? That is suprising. For me fast/block takes 8.2s, 1.5s is
spent in this particular test. Fast/block is generally one of the
fastest sets, http set takes 50s for 184 tests, several of which are
slower than this.

But yes, I should probably remove the test since it has so much impact
on slower systems.
