I am intending to start working on this soon.  I agree with the basic
plan of extending the native pointers from int to long, but I'm not
sure about moving the memory management to the native side.

I was intending just to sit down and do it.  It may be that we could
co-operate in some way.  Perhaps you could fix the memory management
code in the way that you intend while I'll find and fix all the
pointers and do the appropriate casts.
