Shared libraries

	I couldn't pass this up. The Spartans, in fact, were successful
because they did live a simple, elegant, ummm, spartan existence. It was
their success, and the ensuing "fat dumb & happy" way of life that resulted
from their success that did 'em in. There's an obvious witty remark about
"those that do not study history..." I suppose I could make here.

	I somewhat disagree. The trick is to take a step back - forget
the bloody shared libraries and develop a system with a decent virtual
memory system that allows nice shared memory, memory mapping, and copy
on write type semantics for those pesky data areas, and shared libraries
are less of a problem. If you look at your watermelon/kernel and ask
"how can I add shared libraries" you'll wind up with a kludge.
