I think your code has different semantics than exist currently.
For example, let's use the example of asking for "slip%d" then "eth%d".
The existing code would hand out "slip0" then "eth0", but your code would
deliver "slip0" then "eth1" which is not correct.
Or did I miss something clever in your algorithm?
