+CPAN.pm can introduce some randomness when using hosts for download
+that are configured in the urllist parameter. Enter a numeric value
+between 0 and 1 to indicate how often you want to let CPAN.pm try a
+random host from the urllist. A value of one specifies to always use a
+random host as the first try. A value of zero means no randomness at
+all. Anything in between specifies how often, on average, a random
+host should be tried first.
