So you don't think there should be an intervening 4.1 release?

I wonder if you could elaborate on this ambitious goal a bit more.
While I agree that the number of globals should be reduced, if only
as a matter of aesthetics, I am not convinced that the goal of invoking
multiple parallel copies of the main gnuplot within the same process
context makes any sense.  Wouldn't it be easier just to fire up multiple
separate copies of gnuplot?

Consider, for instance, the terminal tables and terminal-specific
globals. Is terminal state persistent across wholesale save/restore
of the program state?  Or does each program state have its own
set of terminal tables? I don't quite see how that 2nd option would work.
