https://github.com/couchbase/EnyimMemcached/blob/master/Enyim.Caching/MemcachedClient.cs#L890
The line in this code can throw ObjectDisposedException that is not handled in the Memcache Client Code. Since this code is executed on a thread NOT owned by an IIS Context Thread, this un-handled exception terminates the worker process as can be seen in our Application Log.
