New bugs are always possible!  And in the last few months, Simon has
been doing fairly major surgery on parts of the runtime system, as part
of getting multiprocessor-GHC to play nicely.  

So if you can find a test case where GHC is generating code that uses a
lot more memory than it used it, it would be very valuable to us.
