Hmm.. while I've been very happy with your (DE) original proposal and
the thread (with Ivan's nice small patch), I'm not sure I'd agree here.

Yes, you and I and a few handful more of people on the globe run
more than one *interactive* R process simultaneously.  But even
there, e.g., when I run  R-patched and R-devel, I'd sometimes rather keep
the two processes "separated", including their graphics windows,
because one important side condition of the workflow is to be
careful in comparing the two R versions.

And R is not firefox (where I really typically only want one
firefox running, already being a crazy process generator and
sometimes memory hog). 
The two (or more) different R processes are entirely autonomous
(in > 99.5% of cases), and I would rather have the current
proposal than a possibly quite a bit more complicated one which
I personally often would not even prefer...

With many thanks to Dirk, Naras, Ivan and Duncan for dealing
with the issue so nicely,
