"pause mouse close" almost works, but not completely

[Dima K. <gn...@di...>]

Hi.

A debugging question. I have a trivial gnuplot script; the specific
script doesn't matter. For instance this in tst.gp:

  plot x
  pause mouse close

What I'd like to happen is to run

  load "tst.gp"

then an interactive plot pops up (x11 or qt or wxt terminals in my
case). When I close the interactive plot (by pressing 'q' for instance)
I'd like the 'pause mouse close' command to exit, and I'd like to get
back to the "gnuplot>" prompt. In my case this doesn't happen. With 'q'
the interactive plot window does go away, but gnuplot doesn't go back to
looking for input. I can press "enter", and I get the prompt back then.

Some minor debugging tells me that after 'q' I still have a gnuplot_x11
helper process. Both gnuplot_x11 and gnuplot are sitting in select()
waiting for input, and I need to kick the selects with another "enter"
to get a prompt back. My gnuplot comes vanilla from Debian. Is this what
people are observing? Any obvious causes? I'd like to ask before diving
into a debugging session.
