Bug 109702 [IDE] [Progress] startup workspace refresh blocks ui
the refresh action at startup of eclipse blocks the ui and cannot be moved into background. this is a similar problem as mentioned in bugzilla 82406 for the package explorer. only the refresh out of the navigator view has the possibility to switch to background.
