TODO: <a href="https://golang.org/cl/166960">https://golang.org/cl/166960</a>: use lock-free structure for Pool stealing
Large <a href="/pkg/sync/#Pool"><code>sync.Pool</code></a> no longer increase stop-the-world pause times.

TODO: <a href="https://golang.org/cl/166961">https://golang.org/cl/166961</a>: smooth out Pool behavior over GC with a victim cache
<code>Pool</code> no longer needs to be completely repopulated after every GC. It now retains some objects across GCs,
as opposed to releasing all objects, reducing load spikes for heavy users of <code>Pool</code>.
