In practice, we've found it to be a non-issue for network and I/O oriented applicative code. We've got a dedicated "sched.wait()" API to force a reschedule, but we never have to use it. We had to tweak os.execute(), Lua sockets and a couple of similar core functions so that they either yield or run in a separate process, though.

I think it will remain a non-issue in Lua: heavy computations tend to occur in C, not in Lua.
