It remember something.
I wonder if we can try to release a binary version of the DaVinci VM,
let say 2 weeks before the JVM Summit.

The idea is to coordinate our schedules to produce a set of patches
applicable on the same VM version. If we got that I will be able
(and I think I won't be the only one) to produce a runtime that
use the corresponding features on non trivial examples.

I've done that for the FOSDEM last February but
I was not able to have all patches working for c1 and c2 on Linux.

My idea is to do a binary release with at least indy, coroutine, tail calls
on Mac, Linux, Solaris and Windows.

What do you think ?
