Alpha!!!!

[Eric Cushman Hill <eric>]

Here it is!!

/usr/local/share/xanadu/backend/alpha-1 now exists!!

Alpha has Documents & Links, stores the database in a file when the backend is
terminated, supports frontend connections via sockets, and is only very as
opposed to outrageously memory leaky.  (Marcs will explain this subtilety in
an upcoming memo.)

One function, backFollow, is still outrageously leaky, but I intend to fix
that for alpha-2 in the next couple of days.  As the immediate needs of the
frontend crew do not include backFollow, this shouldn't be a problem.
