I didn't have anything to do with the change, but for what it is
worth, it was definitely not my intention that calling R() twice only
creates one interface.
When I designed and implemented the interfaces, my intention was that
it be possible to create multiple interfaces to multiple copies of R
(or to any
other pexpect interface).
