Current script check-url.pl checks URL found in 856$u by sending HTTP
requests, one by one. The next request can't be sent before the previous
one get a result, which can be very slow for dead URL. I propose a new
script which send multiple requests simultaneously which improve
drastically URL checking execution time.
This script is based on AnyEvent and AnyEvent::HTTP CPAN modules.
Add new dependencies AnyEvent & AnyEvent::HTTP.
