skipping slow/unreliable servers when fetching

Hello all,

I retrieve messages from a number of servers (nnimap, nnml, nntp).  Some
of the nntp servers are not very reliable and often time out.  This
causes gnus to stop fetching messages and I have to ask again.  Is there
a setting that will allow gnus to simply continue with all other servers
and update the group buffer accordingly?  I don't particular care if the
less reliable servers time out or not in general use.

Thank you,
eric
