Gee, how could we ever have lived without that for two decades? :-) Maybe because we don't need it and it doesn't buy us very much? While we are getting away from hw.arch, this is a sensible sw.arch question. I beg to differ with you on this. mmap() is a huge win, in performance, in conceptual simplicity for the obvious uses in speeding up IO and also it allows for a very elegant way for different processes to share common memory under dynamic program control. -- Keith H.
