qemacs (unfortunately unmaintained) uses mmap(). I tried reading a 450MB file in memory, and it alternately acts very responsively and locks up solid for up to a minute at a time. It also fails to find search strings at the end of the document if I am at the beginning.
emacs takes a few seconds to open the file, but when I was at the top, it found a search string near the bottom quite readily. It does not seem to lock up for more than a second or two. This is an opteron workstation with 2GB RAM, so I guess it's not exercising the swap.
