Roger, I haven't looked too closely at the guts of the forall implementation,
but your analysis and 3-loop strategy to fixing the bug seems reasonable. In
fact, most of the forall code may be the original code implemented by pbrook.
I particularly like the concept of "make it work and then worry about
optimizations". One thing to keep in mind is that the forall statement is
a parallel assignment operation. You may be able to take advantage of the
tree-vectorize work for the inner loop.
