Another example is Niue: http://vmathew.in/niue/docs/niue-lang.pdf

It uses !! (spawn) Executes a code block in a new process.
Pushes the process id of the new process on to
the data stack of the parent.

I am a bit worried about having to keep track of those process id's
and I am not convinced that it must be asynchronous message passing.
Also, the Sieve example:
http://rosettacode.org/wiki/Sieve_of_Eratosthenes#Niue
does not use the message passing.
