Thanks, point taken.

Now in https://github.com/nonsequitur/inf-ruby/issues/121
we came to the conclusion that another patch is needed for ob-ruby.el.

This patch should allow sharing the same :session among code blocks
for the same root dir only when :session is nil.  But in case of
a named :session, its commands always should be encapsulated
within the buffer with the same name as :session.

Therefore I'm submitting the patch here for inclusion
to the Org repo.  Thanks in advance.

Subject: [PATCH] ob-ruby.el: Don't reuse the same buffer among different named
 sessions

* lisp/ob-ruby.el (org-babel-ruby-initiate-session): Instead of
run-ruby that always insists on using the existing buffer, use
run-ruby-or-pop-to-buffer that allows using the buffer with the
same name as :session header arg.  Use the existing buffer
returned by inf-ruby-buffer only when :session header arg is nil.
