Bug#658937: testing.pl: needs rewriting
migration/testing.pl needs to be updated to make it react better when
called repeatedly, or to avoid the need to do so. Right now it's
sufficiently resource hungry to make a 16-core machine unhappy.
An initial idea might be to statically generate package pages, although
this would need to be benchmarked for feasibility. testing.pl could
then simply become a redirect to /package/blah or similar.
