[Kss-devel] Another CSS selector test

[Alec Mitchell]

This is indeed very useful, it's pretty clear that cssQuery is pretty
sub-optimal.  I got similar results with mootools and prototype nearly
tied in FF (in both cases mootools was slightly faster though), with
dojo and ext 3-4x slower, and jQuery and cssQuery >15x slower.

In Safari, he results were a bit different.  Ext was the fastest, only
slightly slower than it was in FF, dojo was 2x slower than than,
mootools and prototype 3x slower, and  jQuery and cssQuery again
unusable at >7x slower than ext.

I have no idea what this all means, and its interesting how different
the relative perfomance of these libraries is across js
implementations.  The only obvious conclusion is that cssQuery is a
complete dog, and jQuery should be avoided if selector performance is
a consideration (for KSS it's one of the primary considerations, IMO).
