------- Additional Comments from Zoltan Horvath <zoltan at webkit.org>
This is the patch to enable TCmalloc for the Qt port. I tested it on Linux and
Windows also and it works well.

Qt-linux performance results:

SunSpider
System malloc 769.48 +/- 1 %
TCmalloc 762.66 +/- 0.7 %

TC 0.8% faster
-------------------------------

V8
System malloc 3580.2 +/- 1.7 %
TCmalloc 3507.6 +/- 2.2 %

TC 2.1% faster
-------------------------------

WindScorpion

System malloc 18722.3 +/- 1.5 %
TCmalloc 17435.1 +/- 0.7%

TC 6.9% faster
