-// TODO I noticed a small benefit to using a larger exclusive pool for batches.  Its very small,
-// but seems to be mostly consistent.  There is a lot in flux right now, but we should really
-// revisit this when batch is everywhere
-
-
-// We use a global pool protected by a mutex(spinlock). Chrome may use the same GrContext on
-// different threads. The GrContext is not used concurrently on different threads and there is a
-// memory barrier between accesses of a context on different threads. Also, there may be multiple
-// GrContexts and those contexts may be in use concurrently on different threads.
