Mmmm.  I'm not sure I understand.  It appears that this is toolkit-agnostic, 
since I might not be running any higher-than-Xlib toolkit (i.e. I'm running 
blackbox and have 3 xterms open, for instance).  What exactly needs to happen 
to get an application to change the cursor theme used within it?  Is this a 
window manager function?  What would make this change possible, exactly?  I 
mean, if $XCURSOR_THEME or Xcursor.theme were to be changed on the fly in a 
running application, would unmapping/mapping a client window make the change 
take effect?  Or are these things only looked at by X when the window is 
first _created_?
