I took it to mean it forks per connection. The quote below is talking
about threads in a client application sharing a connection to an Rserve
server. Assuming I didn't misunderstood that much, it implies R can
handle non-eval commands in parallel, (which in turn would imply that
RInside would also be okay).
(That may not be the case if Rserve is serializing the incoming requests
on each connection... but in that case there would be no need for them
to have written the "don't eval in parallel" warning.)

A chain of assumptions... it be nice if someone had actually tried it.
(If no one else has, then I will get to it; eventually.)
