Need help with parallel to pause a function/coroutine while a variable is set

local tUserInput = {
  ["key"] = true,
  --#add stuff like mouse_click, char, monitor_touch, etc. here
}

local tRunning = {}

local maxID = 0

local function addToRunning( func ) --#simple.  Just pass this a function, it adds it to the table.
  local co = coroutine.create( func )
  tRunning[ #tRunning + 1 ] = { co = co, id = maxID + 1, bUserInput = false }
  maxID = maxID + 1
  return maxID --#return something to identify
end

local function setUserInput( id, b )
  for k, v in pairs( tRunning ) do --#find a thread that matches the id
    if v.id == id then
      v.bUserInput = b --#set the user input (true for "I want this to receive all events", false for "filter out user input")
      return true
    end
  end
  return false, "Not a valid coroutine ID" --#if it's not found, report the failure.  I didn't want to error, because that causes problems.
end

local function runAll() --#this works like parallel.waitForAll, it'll run until it has no more coroutines
  local event = {}
  while ( #tRunning > 0 ) do --#tweak this limit to change the behavior to match parallel.waitForAny
     for k, v in pairs( tRunning ) do
        if (event[ 1 ] == v.filter or not v.filter) and (v.bUserInput or not tUserInput[ event[ 1 ] ]) then --#if the coroutine doesn't have a filter or the event in queue matches the filter AND the program accepts user input or it wasn't a user input event,
          local ok, v.filter = coroutine.resume( v.co, unpack( event ) ) --#resume the coroutine, set the filter to what's returned by coroutine.yield (this is how the event system works)
          if coroutine.status( v.co ) == "dead" then --#if the coroutine has finished
            table.remove( tRunning, k ) --#remove it
          end
        end
     end
     event = { os.pullEvent() }
  end
end
