after revisting the code in question I remembered why - pf_tag_purge() 
traversed the list from the end and could prevent ID space 
fragmentation in the typical cases.

However, inspired by this discussion, I changed the ID allocator, and 
it does this job now, even better and last not least faster than 
before. pf_tag_purge() is gone.

Thanks for the inspiration ;-)
