A quick scan though the mailing list archives didn't reveal any reference to this article, so here goes:
http://ridiculousfish.com/blog/archives/2006/05/16/36/ In response to a criticism of OS X, a diligent blogger examined a claim that it was an inherently slow operating system. The application in question was R, and the results were... "Linux uses ptmalloc, which is a thread-safe implemenation based on Doug Lea’s allocator (Sekhon’s test is single threaded, incidentally). R also uses the Lea allocator on Windows instead of the default Windows malloc. But on Mac OS X, it uses the default allocator." ... and ... "If you use the same allocator on Mac OS X that R uses on Windows, the performance differences all but disappear." Would it make sense for the build process that generates R binaries for OS X to use the Lea allocator?
