Yep I mean 1)
  lists that usually arnt that big. which is not always so easy to 
define  since scriptlinks, and modifiers have no limit.
But I think its safe to say that anyone with 100+ scriptlinks 
experiencing some slowness can live with it.

My guess is it would probably be 1000+ where would get to realy 
noticeable slowdowns that could effect usability of a script.

Keep in mind many people use "ob.data.name" and dont notice its 
converting 10000's of elements to NMesh each time.
