 Sorry, here is an updated version with confusing comments removed, slightly
reogranized and one possible bug fixed. No known bugs left :) Though I didn't
try to use funny session names containing special shell characters. Tested on
RH62.

 I think it's best to name this session script Gnome-MultiSessioned so that 
users who don't need this advanced functionality will be able to use
plain "Gnome" session script and won't be presented with choice
dialog (that slowdowns session startup since input is expected).

 What do you think about this?
