Adding a tiny 4 slot LRU for deferring command buffer object releases.
Now that we have only a handful of buffers in use at any given time this
LRU cache prevents almost all redundant retain/release actions. Total
memory consumption (and the reallocations required to get up to the
previous max) went from 96KB in bert to 4KB.
