I disabled the delete-package stuff in the CVS version.  Deleting old
packages was supposed to avoid confusing error messages, but it is
actually more confusing than not to deleting them.  There's a new
function

    swank-loader:init &key delete reload

which can be called with :delete t to force the deletion.
By default it doesn't delete anything.  By default, it also doesn't
reload swank, if the swank package already exists.
