crash in delete_window

[David Reitter]

I just had a crash in delete_window and thought I'd do something about it 
before/rather than filing a bug report....  From the trace below, it seems like 
Fdelq is called, followed by a process_pending_signals and some redisplay, 
which probably crashes because the window has been half-deleted.  

Would it be sensible in this case to add some BLOCK_INPUT statements to 
delete_window, or maybe SET_FRAME_GARBAGED?  (Sorry if this is a naive 
suggestion.)
