this doesn't appear to be a locking/concurrency problem, it looks like a
infinite loop locking up the EDT while it keeps running.
I am not sure if this should be on the EDT on the first place, but this
wouldn't solve the issue anyway. @jlahoda @dbalek any thoughts?
some thread dumps after it freezes from mouse click (on the iterator
completion) and up:
