Many thanks, this is really interesting

I see. A last thing which I'm curious about is the executable
size. If this can be compared to a Windows dll at all. Did you 
compile without the changes for your target as well? 
How is the ratio? The python15.dll file contains everything
of core Python and is about 560 KB large.
If your engine goes down to, say below 200 KB, this could
be a great thing for embedding Python into other apps.

ciao & thanks - chris
