We should investigate and seriously cleanup the cmake manager code. 1314294 11 mail 2012-11-10 17:30:19 +0000 Git commit b867b9b0327a5a4eec625fb94f37140951d1d56f by Milian Wolff. Committed on 10/11/2012 at 18:27. Pushed by mwolff into branch 'master'. Don't trigger reload of project that is being reloaded. That can lead to crashes and random races due to the messed up thread handling in the cmake manager code.
