Code review comment for lp:~compiz-team/compiz/compiz.fix_1085591

I still get bug 1085591 even with this branch. Seems like nothing is fixed.

1. Start compiz
2. Start another compiz --replace
Expected: Compiz is replaced
Observed: The old compiz is killed but the new one fails to start with:
compiz (core) - Error: Another window manager is already running on screen: 0
