http://hg.netbeans.org/core-main/rev/dad5c2621a49

the main idea is similar to deadlocks + broken models in navigator.. keep a private instance of the model and only sync it at explicit points, not relying on the automatic synchronization in the managed models. so yes, we keep more memory around but at the same time hopefully successfully workaround the broken xam multithreading model.
Comment 3 Quality Engineering 2012-09-13 02:10:14 UTC 
Integrated into 'main-golden', will be available in build *201209130001* on http://bits.netbeans.org/dev/nightly/ (upload may still be in progress)

Log: #216545 use a fresh private model for the status provider, only synced at well defined times.
