That would help the Wiki side maybe, but probably not us. We do ATM one 
call per link. I only see a speedup when we could get all the i18n links 
at once somehow. I check the docs, but didn't find a solution.

There is an easy way for speedup. Use WWW::Mechanize instead of wget 
calls. But that increases the frequency of page calls and is not so good 
an idea. That's exactly what I use as rule to block IPs and WIKI admins 
wont be so different :-)
