      This is an evil hack to work around a bug in gnome-vfs:
      gnome-vfs seems to not properly lock partially-constructed

      gnome_vfs_async_cancel, it is possible to start to destroy
      an object before it is totally constructed.  Hilarity ensures.

      This is an evil and stupid hack, but it slows down our reload
      requests enough the gnome-vfs should be able to keep up.  And
      given that these are not instantaneous operations to begin 
      with, the users should be none the wiser. -JT
