[EasyCachingAble] is suspectible for cache stampede problem? #534
Description
Seems to me like using EasyCachingAble attribute for cache isn't protected against cache stampede problem where multiple calls at nearly the same time before the cache is created are causing multiple cache refreshes. One solution would be to lock cache refresh entry with semaphore slim (Locking in https://en.wikipedia.org/wiki/Cache_stampede)
