To waffle, ‘to waver, to vacillate, to equivocate, to dither’

Speaking (in sci.lang) of Andy Grove, he uses waffle in the above sense in his
good, well-edited ‘High Output Management.’ In my youth I would only have used
or understood the word in the meaning ‘to ramble on, to say nothing of much
consequence,’ and OED2 documents that the fail-to-make-a-decision sense is
colloquial or non-standard.

I presume I have misunderstood various Americans over the years in not picking
up on the ‘dither’ meaning. How universal is that meaning over there?
