Please disregard the above.  First, I just reproduced the
problem on 2.2.7-RELEASE.  Second, I discovered that all it
takes to make the zombie go away is to move the mouse cursor
over the root window.  I guess olvwm was sleeping and the
mouse event woke it up, at which time it found out about death
of child.
