.animate() when used with large groups of elements is not "in sync"

Description

Brought up by polyrhythmic in IRC - and also here: http://www.splashnology.com/blog/jquery/237.html

A simple test case : http://jsfiddle.net/gnarf/GfUZf/

The internal jQuery.fx.custom() assigns jQuery.now() to each elements animation as its startTime, which as the ms add up to calculate start/end positions, creates a "drifting" effect on the large animation.

https://github.com/gnarf37/jquery/commits/animate_fix proposes one solution to this - allowing (and defaulting to) a synchronized startTime that gets passed down the line via the "speed" object (which becomes this.options in the .fx)

This is addressing a similar problem to 6281 but with a different, probably more-user-friendly approach...can you file a pull req?
