I have a loop in my program and at each iteration I'm creating a plot that
is displayed. But since there are more than GP_MAX_TMP_FILES iterations I
get an exception. How do I properly clean up the temporary files in each
iteration?

What steps will reproduce the problem?
1. Create more than GP_MAX_TMP_FILES plots.

What version of the product are you using? On what operating system?
I'm using the latest version running on linux.
