It doesn't work right now because you need to set library properties
that we had not defined yet (e.g. these is no omp_num_threads variable
yet).  Also the schedule environment variable isn't implemented yet. 
Also, reading the environment should somehow just be part of the library
initialization.

So, it was just an example of how it *could* be done.  It's quite easy
to actually make it work, though.
