Hmmm... Still not seeing os.close(fl)...

os.remove() will remove the lockfile name from the directory. It
doesn't automatically close the file.

When I was still maintaining it, it worked with 2.5, and I distributed
a patch you could apply to get it to work with 2.4. I'm not sure if
the current maintainers have changed that. You'd have to look. If
worse comes to worst, I believe 0.9.1 (the last version I released)
should still work with 2.5.
