...ver, even though my pass is run (and executed immediately before the client pass that is calling AA.doesNotAccessMemory(F)), the queries never reach my implementation. What am I missing?

Hi, I like to produce a series of levelplot graphs in postscript file, so I put the trunk of codes including postscript() and levelplot() in a for loop.
