	<rdar://problem/3942428> reproducible crash loading cbs.sportsline.com

	This change reverts the fix for <rdar://problem/3805311>, and
	re-fixes it in a different (better) way. Instead of preventing
	programmatic open from setting the parsing flag, instead make sure
	that programmatic close resets it.
