Module pool 

Per-loop buffer pool in size classes.

Buffers are plain Vec<u8>s whose capacity is exactly one of the class sizes. BufPool::get hands out an empty buffer of the smallest class that fits; BufPool::put takes it back for reuse, up to a cap per class (beyond that, or for a capacity that is not a class size, the buffer is freed). A pool belongs to one loop thread, so there is no locking.
