running org.netbeans.modules.java.source.save.Reformatter.reformatImpl()	92.079216	38,285 ms (92.1%)	38,285 ms under a document write lock, diff is merely waiting for a read lock.
Can the reformatting spend less time under the write lock? Or maybe better, can org.netbeans.modules.editor.lib2.view.ViewUpdates.updateViewsByModification()	49.36628	20,525 ms (49.4%)	20,525 ms update views only after the reformatting finishes?
