      when you show some toplevel window, sometimes it
      takes several seconds for it to become visible. During this time, the
      application is frozen - if there are other AWT toplevels you won't be
      able to interact with them.

      You can observe this problem with test/java/awt/Frame/DisposeStressTest
      - run it on Solaris/CDE/dtwm and notice how quickly frames
      appear/disappear, how fast other windows on the screen blink because of
      focus changes.

      Now run it either on Solaris/Gnome or Linux/Gnome/Metacity and notice
      that sometimes the applications freezes for sometime - no new window
      appears on the screen, and other windows(try Instructions dialog) are
      unable to receive focus. If you obscure their content during this time
      they won't be repainted. This happens with both XAWT and Motif toolkits,
      with 1.4.x, 1.5, probably with some earlier releases as well.
