Modified files:
	cm3/m3-ui/vbtkit/src/lego/POSIX/: ScrollerVBTClass.m3 

Log message:
	Fix crash reported for PPC_DARWIN.  Rescreen can be called by other threads
	while another thread is in the middle of Repaint, and Rescreen may set
	v.shadow to NIL, which makes Repaint very unhappy.  Lock v.mu to prevent
	unsynchronized access/changes to v.shadow.
