I'm not sure I see how that risk would happen. It would be only the two system 
Rubies that install to ~/.gem/ruby/<version>/gems.

True, but it would be nice if the system rubies could use the same gems, whether 
or not they're being run through rbenv. I would like to avoid having more copies 
of gems installed than necessary.
