Logically sync() should return only after all dirty buffers that
existed before sync() was called are flushed.

Anything more than this (i.e. waiting on newly (since sync was called
but before it returns) dirtied buffers) could live-lock (actually,
this used to happen sometimes, I don't know if that's the case).
