Out of curiousity, do you have an empirical data to compare running time/memory and precision of receiver-insensitive 
call-graph v/s receiver-sensitive call-graph?  (The time and memory are inclusive of all the analyses that lead to or are 
required for call-graph construction.)

Also, by context, do you mean call-string/call-stack?  If so, do you do some sort of limiting on the length/size of the 
context?  Do you have any empirical data about cost and precision?

waiting for reply,
