Update of /project/mcclim/cvsroot/mcclim In directory clnet:/tmp/cvs-serv15466

Modified Files: sheets.lisp Log Message: clim:graft should return nil for degrafted sheets. Also, strengthen conditions necessary to process configure-notify for toplevel sheets. This should reduce or eliminate 'No applicable method for generic funciton clim:graft with arguments NIL' errors when closing the listener, due to a race condition between disown-frame and the CLX event thread.
