I did clean rebuids with and without, and then ran the parse-only sunspider
suite.  the individual runs resulted in numbers that varied enough that the
results didn't appear significant (sometimes "new" was better, but ~usually~
"old" was better).  So I ran the parse tests 20 times in a row, read the
results, and calculated the mean and stdev the same way sunspider does (throw
out first run).  Here are the results:

before grammar change:

                  mootools-1.2.2-core-nc  mean:   7.9  stdev:   1.9
                            jquery-1.3.2  mean:   7.7  stdev:   1.6
                       prototype-1.6.0.3  mean:   9.1  stdev:   2.6
        concat-jquery-mootools-prototype  mean:  24.8  stdev:   2.4


after grammar change:

                  mootools-1.2.2-core-nc  mean:   7.9  stdev:   1.8
                            jquery-1.3.2  mean:   7.8  stdev:   2.1
                       prototype-1.6.0.3  mean:   9.7  stdev:   3.4
        concat-jquery-mootools-prototype  mean:  26.4  stdev:   4.3

the grammar change seems slower, though the stdev is larger for the slower
results as well.

No chance we can get a higher resolution timer, is there?
