Isn't this precisely what the language Concurrent C attempts?

   "Concurrent C is the result of an effort to enhance C so that it can
	be used to write concurrent programs that can run efficiently on single
	computers, on loosely-coupled distributed computer networks, or on
	tightly-coupled multiprocessors.  Concurrent C is an upward-compatible
	extension of C.  These extensions include mechanisms for the declaration
	and creation of processes, for process synchronization and interaction,
	and for process termination and abortion."
	_The_Concurrent_C_Programming_Language_, Gehani & Roome, p. xii.

Anyone know any more about this language?
