This is necessary for an optimization in Warp, where we already have a
pool of raw buffers available which I'd like to reuse for blaze-builder.
Relevant issue: yesodweb/wai#198
Expose the Buffer constructor.
If this patch is acceptable, a quick release including this patch would be appreciated.
Sorry for the delay. Released as 0.3.3.0.
Thanks! It works for me.
