Re-2: [ObjectWeb architecture] just an idea for (Java) native compilation

[<markus.karg@xxxxxxxxx>]

Oh, now I understand. So is the OCaml compiled native code faster than the 
code from other compilers, e. g. from GCJ? Do you have benchmarks (I'm really 
interested in getting Java running faster)? For the second point: Sure 
constructing an ObjectWeb own native java compiler is interesting, but do we 
have manpower for such a project?
