描述

Many of the backends create temporary files and/or open file handles with open without cleaning up either. While GC will eventually deal with the file handles, some OS's require you to close handles before you're allowed to delete a file. And accumulating an unbounded number of files over time isn't a nice thing to do to users' temporary directories.

研究方向
Look at the backend implementations in Plots.jl, particularly those that create temporary files or open file handles. Check the source code for `open` calls and ensure corresponding `close` calls exist. Consider using a try finally block or a resource management pattern. The issue has comments suggesting possible approaches; review those for guidance. Files to examine include the backend modules in src/backends/ directory.
