Thanks, I just added this to CVS.  Sorry I didn't get it into the release.

The temporary-file removal problem is discussed in FAQ.txt.  Under what 
circumstances exactly did calling close() help?  It would probably make 
more sense to add a close() method to the GnuplotProcess objects because 
its implementation is likely to be platform-specific.  Then I guess 
Gnuplot should call the close() method in its own __del__ method.  Hmmm, 
I guess this helps by ensuring that the pipe is closed before the 
plotitems are destroyed.

OK, I just implemented this in CVS, too.

Thanks for your note and suggestions!
