[racket-dev] proposal: `data' collection

That would be interesting and it would not be terribly difficult to
instrument setup-plt to do it.

I can't promise to have any time in the lab between now and the beginning of
my time at the University of Utah, so if you'd like it done anytime soon, I
won't be of much help.

Wouldn't the more interesting thing be to measure the connectivity at the
collects level (not the files) and to discover cycles in this graph? --
