Dan,
I haven't seen it documented, but it is implemented. The only
reason you go into debt is when your Bc is less than the packet size.
The algorithm will still make you pay back the debt though. Originally
when FRTS was introduced they overlooked the issue, and packets with a
size greater than Bc would be stuck in the output queue indefinitely.
