GUI freeze for large file sets, propagates to gnome-panel

[dronus]

If run from a gnome-panel desktop, the already annoying GUI freezes for large sets of files (eg. 'Select All' for hundred thousands of files) propagate back to the gnome-panel, making for example window switching impossible for a few seconds.

I think we have a big problem if an application's operation renders the global panel unresponsive. Especially if dependent on the size of data sets. A some million file directory would stall the system responsivity for a long time, rendering the whole system unresponsive.

Is this unisons's fault, or gnome-panel's?
