Thinking some more about this, I seem to recall the change was made because of interactive bindings. For example, if you are using octave and pressed the close button then the call to plabort would kill your entire octave session which is clearly not desirable. We definitely don't want to apply my patch as is. I need to work through all the tidy up code in xwin.c to check exactly the path that is being followed. The current code is doing the right thing in terms of closing the window and ignoring all further commands to the plplot stream, we just need to ensure that the tidy function is called at the end. A clean way of doing this would be to have multiple levels of stream_closed. 0 = open, 1 = closed, but still need to call tidy, 2 = closed and tidy already called. Only the xwin and cairo drivers set this flag, but it is checked in the core plplot code. I can simply implement this change Alan, but your call whether you want to commit it at this late stage. It should be trivial.
