[boost] [Signals] Named slot group usage?

I'm trying to determine how widely used named slot groups are in the 
Signals library. I would appreciate it if I could get some feedback on 
if they're used, how they're used, etc. In particular:

        (1) Do you use named slot groups?
        (2) Did the FIFO ordering guarantees in 1.32.0 and the ability to add 
to the front or back of the slot list alleviate the need for named slot 
groups?
        (3) If performance of connection/disconnection of named slot groups 
were to get worse (e.g., linear in the number of slots), would it 
seriously impact the performance of your application?

Responses should probably come to me, personally, unless they would be 
of interest to the group.

Background: Signals performance is sub-par, and much of the problem can 
be traced back to support for named slot groups. I'm trying to 
determine the best way to proceed.

        Thanks,
        Doug
