Hi Geoffrey, I used to work on memory related topics, while I was working on the University of Szeged.
Based on a 2.5-year-old measurement ( http://webkit.sed.hu/blog/20100302/war-allocators-qtlaunchers-coast) on the Qt-port, the page loading on the Methanol test suite was 5% faster (avg) with TCmalloc than the default system allocator on Linux. The performance results of the SunSpider suite was similar for both allocators. The memory consumption was always lower with the default os allocator. I guess the new allocator only has iOS support. I'm fine with removing TCmalloc, although this direction might raises further questions, like removing the custom allocation framework also. Feel free to cc me on bugs, I can help by contributing some patches.
