There has been discussion about this though in the linux-gcc mailing list. There are patches now available that allow Emacs 19.30 to use Doug Lea's mmap-based malloc in Linux libc-5.3.5. It helps, but is not worth writing home about. I mailed rms a copy of the XEmacs ralloc.c this past weekend. Since it is already copyright assigned to the FSF I would expect it has an excellent chance of appearing in a future version of Emacs. None of this means that effort should be relaxed on cutting down the excess garbage in Gnus. My tests indicate that Gnus easily defeats mmap mallocs at present.
