But neither is there anything left to stop that from happening Really
Soon Now(TM). Nothing under gnuplot's control, that is. BTW: what
terminal driver are you talking about?
I.e. gnuplot returns to the prompt because its job is done. If, after
that, it takes any time long enough to even notice for the plot window
to actually show up visibly, that means one of two things:
1) Your window manager insists on you placing every new window manually.
Bad idea for the gnuplot_x11 window.
2) Your machine is sluggish.

I'm not aware of any provisions for such a block. Because of the
possiblility of deadlock that goes with any blocking operation like
that, I'm slightly opposed to it even without having considered at any
depth.
