Ah ok FileReader has a reason to make it strict. (I changed like that since in
FileWriter I didn't see a reason to force the caller to deref the proxy after
abort().)
Added the ASSERT as you suggested in your previous review.  Also added a line
to nullify the client in stop() to avoid calling back on the client after
stop().
