    Huh?! That's exactly what the code does.  I verified it correcly
    breaks such cycles before posting the message.

Now I see why that is so--it is because you update MAPS at the
end of the loop.

But the result is that the code is both more complex and slower
than a simple loop that looks at each element of MAPS.  So would
you please change it to work that way?
