I am running v8plus binaries, which are a horrible mix of v8 and v9 code.

But you are right, "wim" was deleted for v9.  The reason I did the code 
the way I did was because the restore_window() function was updating the 
register (even on sparc64).

So I guess the real fix is to implement proper save_window() and 
restore_window(), and also flush_window().  Then make sure that "ta 3" on 
v9 calls the proper flush_window() code.

As a temporary workaround though the patch I posted seems to work.
