Subject: [PATCH] Accepting request 244786 from home:mcaj:branches:Base:System

- I wrote a patch got-lock.patch to fix the trouble with the got-lock variable.I was testing the withlock and still had there the lock file after a  program already end with exit code 0. I have look on the code together with our Python expert mvidner@suse.cz and we found the got-lock variable  isn't marked ad global variable. We have tested it and with the patch the program is working very well. I send this patch also to upstream (poeml@cmdline.net)
