Immediate respone to a pick hit

[4614]

  I would like to get an immediate response, while in select mode, to a
  selection hit.  That is:

     1) I enter select mode

     2) I traverse my display list drawing entities one at a time

     3) After drawing each entity I check a flag;  If a hit has occured
        the flag is set and I can stop traversing my display list 

     4) After getting a hit I exit select mode and process my pick_buffer

  Anybody tried this?  Anybody have any ideas?
