MSHRs should take care of themselves if you just wait for the outstanding transactions to complete. In timing mode you'll probably have to write back lines until the write buffer is full, then as the write buffer empties, add a check if you're in drain mode and keep iterating until you're all the way through the cache, then signal that the cache is drained only when the write buffer is emptied.
