Both attached snapshots contain FileUtil-Refresh-All thread which may block the underlaying operating system (apple painting in one case, reading of preferences in the other).

I have a reason to believe that after fixes made (bug 184344, bug 184219), the I/O load of the background thread shall be made much less intrusive. Only time can tell whether it will be enough to prevent this kind of slowness, however.
