I don't think you prevent WM_SAVE_YOURSELF from blowing you away. You
have to maken sure that WM_PROTOCOLS window property is not set for 
your application.  In Motif, you should make sure that WM_SAVE_YOURSELF 
is not being set.  For further information, consult the Motif Programmer's
Guide.  In the version 1.0 manual, this is section 8.8.2 Protocol Manager 
Functions.

According to ICCCM (pg 39)
"Clients receiving WM_SAVE_YOURSELF should place themselves in a state
from which they can be restarted ...  No interactions with the user are
permitted during this process."

So if WM_SAVE_YOURSELF is used you can't let the user save the changes it
has made.
