This doesn't work right now.  main() has to do some special
initialization stuff.

Eventually we'll write a CNI version of the invocation API.  That will
let something like the above work.

If you're really interested in this you could design and implement it.
I could provide some guidance on how we'd like it to be done
(basically: more or less a CNI variant of the JNI invocation API).

Take a look at the implementation of JvRunMain.  That will tell you
what has to be done.
