FWIW, I generally like to put a comment on the next line to make it
abundantly clear that there's nothing in the body of the loop, it's
also more aesthetically pleasing than a semi-colon on the line by
itself, ex. /* Nothing */;  It's just too easy to misinterpret the
loop otherwise, especially without gratuitous white space.  Thanks,

Alex
