I've just commited my changes to scipy_core. Now, I must be missing something,
because scipy.linalg still exists and is the same module as scipy.basic.linalg,
not scipy.linalg from full scipy no matter how I try to import things. I'm using
a regular install; not eggs.

I've also moved random.py out into main core/scipy/ directory under the
reasoning that we shouldn't get name conflicts with anything in full scipy. I
think that anything we'd want to add to full scipy wrt random numbers should
either get its own module (e.g. scipy.mcmc, scipy.aesprng) or will fit
comfortably in scipy.stats.

Also, since we no longer want to automatically import things exposed in
scipy.basic.__init__, can we make it an empty __init__.py? That way we don't
waste time and memory importing the fft modules when we only need linear algebra.

Can you do what you suggested? I'm pretty sure I'll muck it up somehow.
