You are of course right, Bill. This is definitely the optimal
strategy for parallelization for (well-written) IDL applications.
Among other things, it definitely scales a lot better with increasing
number of processors than writing a few threads that may execute
in parallell.

The only thing I can say to my defence for not mentioning it
is that it's, well, kind of boring, from a programmers perspective :-)
