Motiviation: At the moment we use FIFO for the PoolThreadCache which is sub-optimal as this may reduce the changes to have the cached memory actual still in the cpu-cache. Modification: - Change to use LIFO as this increase the chance to be able to serve buffers from the cpu-cache Results: Faster allocation out of the ThreadLocal cache.
