[Vala] vala and actors model

[Fabien CELLIER <tallion users sourceforge net>]

Hello everybody,

I created a small wrapper for actor model in vala (just a poc for a friend,
in order to show that multithreading could be easy with glib ).
The code is small and contains, probably, bugs but I won't delete the repo
before next month, so if someone wants to take a look  (
http://beta.intuxication.org/hg/tallion/vactors/file/). The main.vala file
contains a "Hello World"  (vactors run 45% faster on my dual core for big
pictures)
