Subject: non-MPI parallel patch follow-up

This is a patch against 1.7.2 that can be used in conjunction with the
previous patch, or alone. It simply internalizes the checksum of the word,
which increases by 20% the parallel performance used via the previous
method. Simply change the startpjohn script to generate a different filter,
one based on this precomputed sum:

filter() {
if (_chksum % total != rank) word = 0;
}
