not quite, it is a lingering problem. Currently one has to sync aspects
sequentially. For example the CSMDrawer synchronization looks like the
following for that reason:
_pSyncBarrier->enter (_uiSyncCount);
# ifdef OSG_GLOBAL_SYNC_LOCK
_pSyncLock->acquire();
# endif
_pSyncFromThread->getChangeList()->applyNoClear();
# ifdef OSG_GLOBAL_SYNC_LOCK
_pSyncLock->release();
# endif
_pSyncBarrier->enter (_uiSyncCount);
So only one drawer at a time applies the app changelist.
I will look into it so that we can get rid of this global lock and
spin lock the containers while applying the changelists.
kind regards
