Prebinding for DragonFly/FreeBSD-4

[Matthew Dillon]

    Ok, I tried again and managed to build and install OpenOffice on 
    leaf.dragonflybsd.org.  I ran a startup test with and without prebinding
    and did not see any human-noticeable difference, though.  Maybe 0.20
    seconds out of the 5 seconds it takes to startup.

    However, despite the lack of any significant improvement in performance
    I feel that the patch set is clean enough to be incorporated, in particular
    the fact that it is effectively 'optional'.  I can also see that it might
    be of use in the future and might also serve as a launching pad for
    additional features such as recording pre-faulting info and so forth.

    Also, despite the tiny improvement, it might improve certain
    heavily-exec'd environments such as those found when building the world
    or ports, with possible further improvements later.

    And I appreciate all the work Simon has gone and done to implement it.

    So I will be committing Simon's port of the prebinding code, plus the
    suid/sgid security patch I suggested in an earlier email, later today.
