This isn't specific to the sandbox option.  The default options used also 
cause this memory usage.  On a box with 16GB of RAM the translation was 
causing extensive swapping (I estimate a peak memory of ~15GB).  This seems to 
happen during jitcodewriter.

I will also run a comparitive build with python-2.7 and report back...
