	I had problems with nnvirtual even on tiny groups.  I wanted to
combine 3 email groups in which two get 1 message a day and the other
gets about 8.  With about 200 old messages in the groups, and this daily
arrival rate, I found entering the nnvirtual group to be over an order
of magnitude slower than a normal group.

	Additionally, I seem to recall that exitting the nnvirtual group
took an extreme amount of time, which no one else seems to have
mentioned.  This virtual group has 'gnus-show-threads' set to nil, as
did one of the three real groups, if that affects anything.  I use nnml
as a backend, and had set the 3 real groups to level 4 or 5 to hide
them.  The virtual group was at level 2.
