Thanks for the report, sorry about the leak.  I just posted an RFC patch, CC'd 
to you, which I believe should fix the problem.  I did a quick compile test 
on the SELinux module but I am "on vacation" with family visiting so I am 
currently unable to do any real testing until next week.

I've added myself to the bugzilla, but if you are able to do any tests please 
let me know if the patch does or does not solve the problem.

Thanks.
