Thanks for the '+1's. This change is active since yesterday and so far
it seems to work. If we still see hosts timing out, especially when
crawling the archive hosts, we can increase the timeout for archive
crawling to 6 hours. Another option to decrease the number of wrongly
auto-deactivated mirrors is to increase CRAWLER_AUTO_DISABLE from 4 to 6
or 8 crawls.

I will look at those changes after the freeze.
