Yeah, I thought that I had tested against the example ses code at one 
point, but apparently not.  While we're here, note the comment about
dropping the lock multiple times to do copyout.  That can probably be
easily fixed by allocating a temporary buffer to copy everything into
first, but I was hoping to find a more elegant solution.  If you have
any ideas, feel free to try them out.
