I was wrapping an object in wire using a sphere sweep. While it was just
a minor background detail, I had several billion spheres. In my defense,
I was also doing this just to find the point at which I ran out of memory.

In general, though, what is the smallest maximum number of "bunches"
that you can run? I know my card lists 4 work groups, I do not know if
any other cards currently being sold only allow 2, or possibly only 1,
bunch to be run at once.
