One thing that needs optimization is nnvirtual with nntp groups: it
always re-activates component groups one by one, which does a GROUP
request to the server for each group... which is absurdly slow.
(Especially if you have lots of component groups, the server is
Gmane and you don't live in Norway.)

It could instead do a few batches of pipelined LIST ACTIVE commands,
like the nntp backend usually does.
