Soon I would like to implement ".advice" files.  Where a process can add
advice for the compiler when compiling that module.  This will replace
the feedback file used by Jerome for implicit parallelism.

The ".advice" files may contain any advice for the compiler relevant to
that module.  I don't see why the compiler can't update these either, if
it did it the right way.  The advice should be generic, in my case I'm
interested in telling the compiler which conjuncts within a procedure
should be parallelized.

he compiler doesn't have to obey to any particular piece of advice,
(this may depend on it's capabilities and enabled optimizations).  I
don't think this affects what you're doing, but it may be helpful to
