Nadav: I don't think this is right approach for engineering. The time-complexity of re-analyzing addr_taken for each single alias query depends on 1. how many global variable 2. how many occurrence of these global variables. 3. how many queries the compiler have. 3) depends on compiler. You never know what we will have in the following few years. 1 and 2 depends on the
