cmuscheme vs. xscheme

I would like to use cmuscheme to run guile.  I use run-scheme to do
this.  When I start customizing the group cmuscheme, however,
run-scheme gets redefined because xscheme.el is being loaded.  I have
to unload-feature xscheme to fix this.

I'm not sure what causes this.  I found the following in cus-load.el,
however:

(put 'cmuscheme 'custom-loads '("cmuscheme" "xscheme"))

Maybe that is because the groups cmuscheme and xscheme both belong to
the group lisp?

Anyway, I know no simple way around this.  It is unfortunate that both
packages define the function run-scheme as well as other variables and
functions without a package specific prefix.  

Since the run-scheme in xscheme is not autoloaded, I suggest renaming
it to run-xscheme.  The cleanest solution would obviously be a big
renaming...  :(
