Lets share all thsi stuff in a new .js file.  No need to copy/paste here.

Thanks.  I'll land this manually before moving these files to the new PerformanceTests folder.

rC and rF are pretty short variable names.  Generally, we prefer to use real english words rather than abbreviations.  I'll tweak this during landing.

Your patch is also incorrectly based.  Please create patches either with svn-create-patch or with webkit-patch to ensure they are properly based.

??? What is wrong?

I normally use git diff and it works without problems and in this case I used svn-create-patch.

Hum...  Maybe the moves confused svn-apply?  I had to edit the patch manually to get it to apply.

Interesting.  The patch has a strange mix of forward and backward slashes.  Maybe that was the problem?
