This change makes the dialog modal with respect to the child-toplevel, but not to the root window.  
(This isn't good enough because my real application has some other tasks,  I can launch them while the file dialog is up, but their rendering is fubar.)

I experimented a bit and discovered that tkFileDialog and tkMessageBox share this behavior.  
In contrast, tkSimpleDialog does not: it appears to be application modal.  If memory serves, the former use the native Win32 dialogs, but the latter does not.
