qa: add snaptest-snap-rm-cmp This (usually) reproduced a bug where: - we write a big file - snap it - remove it. this makes the mds cow it. - cp the snapped version. - mds syncs the head - client starts writeback - (sometimes!) client sends other caps back to the mds - mds does null flushsnap, not realizing a real one is still coming 2010-08-18 20:44:34 +00:00			`#!/bin/sh -x`
