I think keeping the issue numbers from sourceforge is good and I
don't think we want to renumber them. At this point it would break in
message links and things.

While using the unused numbers would be nice, implicitly the numbers
are expected to match date of creation order, so using lower id's would
mess that up. Again I don't think that's desirable.

I think our limited time is better spent improving the tracker workflow
and roundup and changing/reusing issue numbers doesn't seem to improve
anything.

I'll close this out won't fix in a couple of weeks unless there is an
objection.
