This is something that can be done outside of the Go standard library. Let's do it there first, and then see if it is useful. Closing this proposal.

Note that memory is already allocated from a per-thread cache. I don't see why using a pool would avoid locks. I agree that in some cases it might avoid a GC, but only with considerable care in management of the memory allocated from the pool.
