Coroutine (API)
From ComputerCraft Wiki
Coroutine is a default Lua 5.1 API defined here. As of ComputerCraft 1.3, this API suffers from the problem of potentially spawning Java threads that live forever; therefore, use of coroutines should be minimized. This is fixed in ComputerCraft 1.32+, though. Please list any non-working functions here.
