What's the current position of WebKit on switching the memory allocator? As
described in your blog article "War of allocators in JavaScriptCore", adding
jemalloc makes no sense for Linux-qt build. However, in Windows CE, jemalloc
gives almost 2x speedup in page loading time over the system malloc because the
system malloc is simply too slow.  

Is it okay to use jemalloc at least for Windows CE? If the answer is yes, I
will file a bug for this.
