buildworld -j N issues

[Matthew Dillon]

    Some issues are cropping up with what I believe are buildworld -j N
    bugs, due to the new scheduler ordering processes somewhat differently
    then the old scheduler.

    I'm working on the correct set of .ORDER: directives in the .mk files
    to fix the problem. 

    If you have problems doing buildworld -j N, just do the buildworld without
    the -j N.  I expect to commit fixes later this evening (I'm running
    buildworld -j 4's on four different machines in a loop to try to locate
    all the ordering issues).
