Ok, i'm a bit lost. How does an implicit coroutine suspension look like?
My tasks can relinquish control trough a bunch of calls, easily
spottable (sched.wait, sched.signal, sched.run, and some wrappers around
those). For example I have this helper function ("run on a signal")

--------------------------------------
M.sigrun = function ( f, waitd )
	local wrapper = function()
		while true do
			f(M.wait(waitd))
		end
	end
	return M.run( wrapper )
end
---------------------------------------

If the provided f doesn't explicitly yield (with a sched.signal or
something) it will run atomically. Or you mean, that I should *enforce*
that when used as this, f will not yield?
