sync.pools aka buffer pools.

this puts lots of back pressure on GC trading bursts of speed for a more noticeable pause at a later time bc of the pause-the-world style GC. I'd love to see if this is still the case with the GC improvements in Go 1.5+. One solution is to manually load balance your web services to switch seamlessly between GC pauses (stagnated gc), without this it's almost unusable in real time applications.
