[GE users] NO_REPRIORITIZATION in SGE 6

Sean,

It looks like reprioritization is turned off in SGE 6 by setting 
reprioritize_interval to 0 in the scheduler configuration:

    % qconf -msconf
    reprioritize_interval             0:0:0


I filed an issue in the Grid Engine issues database to remove 
NO_REPRIORITIZATION from the man pages.
