 Do _any_ web browsers have a connection limit lower than 4? Given that
and that we obey the max connections limit of the user and that in the
metalink ... it seems pretty alarmist to say 3 is too many to a single
server.

 You can open an RFE in bugzilla, and we could look at it if it's really
useful information ... one problem though is that we combine all
bareurls+mirrors, and move between them at the urlgrabber layer. So we
couldn't easily just change something on the yum side.
