 Hmm, it looks it has been discussed deeply and fiercely enough for me not 
to dare question the outcome (or the lack of), but given the situation 
wouldn't it be reasonable to place a comment within the code of this 
function stating that outermost frame determination has been deliberately 
omitted so that cases like stack corruption are easier for people to 
debug?
