349b9ce502 Don't post contended accesses other than on the +2a/+3. 
Those machines have an actual latch for this stuff, the others don't.

d77ddaf4fa Switches the Electron to JustInTimeActor video. 
Also reorders template parameters; I think that specifying a different time base is likely to be more common than using a divider.

14663bd06b I think 3 is what I'm aiming for here. 
But this probably isn't correct for IO cycles.
