I'm not sure if any one has responded you in private email, but if I
understand:

Elysium will be microkernel-based exokernel, so there will
be so called LibOS'es on the top of Elysium kernel.
The communication between LibOS'es and kernel could be implemented with
dedicated system call or dedicated memory location in kernel for message
passing.

But actually I would have also some more info about Elysium future vision
etc...

What about this pthreads design status?
