semaphore unlock after timeout

[benanderson_475]

hi, 

is there a way i can i have this to unlock itself after the timeout period executed by the callback?

many thanks,

require('sem')

-- wait for 5 seconds max before executing callback
res1, res2 = sem.runlocked('eventlock', 5, function(lockres)
  -- lock acquired
  if lockres then
    return true, 'lock ok'
  -- failed to acquire lock
  else
    return nil, 'lock failed'
  end
end)

log(res1, res2)
