From comment in TaskSolver.scala:

This method stays within the method (intra-procedural analysis) and terminates at method parameters and at output
arguments

Since the variable path in TaskSolver contains only nodes within the current method,
isArgOrRetOfMethodWeCameFrom will always return false.

Hm... you may be right about that: it used to be the case that nodes on the path can be from other methods, but I believe that was refactored some time in January when I was doing the work on performance improvements of the data flow engine. Give me a bit of time to look at this in detail.
