| // 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. |
