I'm still confused as to what it does.  Is it different than pressing
`A A' in group buffer? 

That server has some 29,000+ groups.

Pressing `A A' in Group gives me. 
some 29,000 lines  1300K of active file

Pressing <RET> on that nntp server in server_buffer gives me some 40 lines

But it displays almost instantly.  And `A k' in group
shows some 15,000 lines

So it is different than `A A'?
