Few calls to org.netbeans.modules.project.ui.PhysicalView$ProjectIconNode.getIcon()	
result in enormous disk activity:
org.netbeans.modules.ide.ergonomics.fod.FeatureProjectFactory$Data.hasFile()

could the 
org.netbeans.modules.project.ui.PhysicalView$ProjectIconNode.swap()
be rescheduled outside of EDT?

only appears to happen with 1.7.0_13 maximum. Might have been an issue with early 1.7 jdks. Please reopen if you encounter with update 21 or 25.
