Test cricket, still the arse-kicking best

Starting in 2005, we have now had four (yup, four) test matches that have gone down to a 9-wickets down draw. Old Trafford 2005 (Aus-Eng), Antigua 2006 (WI-India), Lords 2007 (India-Eng) and now Antigua 2009 (WI-Eng). Has this sort of temporal clustering of the one-wicket-to-get draw ever happened before in test cricket? I doubt it. India have been denied once; England the other three times!
