It may take some time before Sawfish processes that event.  In the 
meanwhile the window would appear to exist.  Using the error handler 
should provide earlier detection, although it is not guaranteed to be 
immediate either, because Xlib buffers requests that do not return 
information.

Faster in detecting windows having been closed by someone else.  Other 
window managers that I have checked do not seem to use this trick, 
relying only on DestroyNotify events.  I don't know why using the error 
handler for this was considered necessary in Sawfish.
