I misunderstood the context.  The same problem would likely occur in
Windows if your application uses R.dll.

I agree that this should be fixed in the long term:  one might want to
instantiate multiple copies of R's evaluator in some application (e.g.
a new front-end that ran multiple consoles), and there should be a way
to shut them down and clean up afterwards.  In the meantime, the
workaround is probably to just keep a list of the activated copies,
and when a new one is needed, check if there's an unused one in the
list.  If so, execute some code to clean up the environment, and
re-use it.
