    No, and most file copies are not to be used in the "near" future. I.e. on
    my machine. Caching on the second read (close in time) is ok, or if there
    are unused ram, but paging out things in use is bad. It's much more likely
    that the page allocated to a program will be used than a newly read or written
    file.

    Ofcourse your milega may vary. I'm thinking of my desktop now.
