AutoRefreshingCache is a MemoryCache which tries to refresh its hot entries before their actual expiration time is reached.
This class gives you a single public method (i.e. GET).
Here comes the pseudocode.


get(param)
	result = cache.get(param)
	if (result == null)
		refresh(param, null)
		return cache.get(param)
	if (result needs to be refreshed)
		result.refreshWorkers.increment
		if (result.refreshWorkers == 1)
			run refresh(param, res.refreshWorkers) in a new thread
	return res.data


refresh(param, refreshWorkers)
	data = calc(param)
	cache.add(key:param, value:data, expiration:exp_time)
	if (refreshWorkers != null)
		refreshWorkers.decrement
