title: Is there a way to mark an InputStream twice?
body: <p>I want to make it so I can call <code>in.mark(512)</code> to limit my stream to 512 bytes. Then, later I want to limit my stream to 64 bytes. Can I later call <code>in.mark(64)</code> and then <code>in.reset()</code> but still have the mark of 512 be active? What I'm trying to say is "Can you have a <code>mark()</code> and <code>reset()</code> stack?"</p>
