// TODO(nick): I think the ideal API would be to automatically increase the
// size of the buffer when we exceed capacity. But this gets messy,
// because each time we get a short read error, we need to invalidate
// everything we know about the currently changed files. So for now,
// we just provide a way for people to increase the buffer ourselves.
//
// It might also pay to be clever about sizing the buffer
// relative the number of files in the directory we're watching.
