Description

If os.pullEvent is called in a coroutine, it hangs and is never resumed by the cooperative scheduler.

I could be misunderstanding something here, so I apologize if I am. My understanding is that calling pullEvent should yield until an event occurs. When an event occurs, the task scheduler should call coroutine.resume(co,<event args>...) on the coroutine that has yielded.

I don't want to use the parallel API because its methods block - I need to run my code in a loop and I want to avoid blocking.

local function CheckInput()
  while true do
    print("Waiting...")
    local evt, key = os.pullEvent("key")
    print(key)
  end
end

local co = coroutine.create(CheckInput)
coroutine.resume(co)  --Start
while true do
  --local _, key = os.pullEvent("key")
  --print("Works in main loop")
  sleep(0)
end

pullEvent works as expected on the computer's coroutine, but it won't work on a custom one. Am I missing something that might put my custom coroutine on the scheduler's queue?
