This may be very difficult.
But if I understood better what your application needs to do,
maybe I could suggest or create a way around the problem.
When you say "batch mode" do you mean:
	gnuplot inputfile.dat
or
	gnuplot < inputfile.dat
or
	gnuplot
	gnuplot> load "inputfile.dat"
or something else I haven't thought of?

For me, the 1st and 3d methods work as expected, but the
2nd method does not.   

If you must use the 2nd method,
perhaps you could use a loop-until-ready construct like this?

main script:
   set mouse
   n=1; set term x11 n; plot x**n
   n=2; set term x11 n; plot x**n
   bind all Home "n=MOUSE_KEY_WINDOW; set term x11 n; plot x**n"
   bind all End "DONE = 1"
   DONE = 0
   print "Hit <End> in any plot window to continue"
   load "wait_for_End"

File wait_for_End would contain two lines:
   pause -1
   if (!DONE) reread

Or maybe it would have to be "pause mouse key" or "pause 1"
or I don't know exactly what would fit in with your intended 
use.
