I couldn't agree more that it is too early to worry about absolute
performance, but I do think we need to be clear that the various algorithms
can be implemented without regressing to algorithms that inherently
require O(n**2) time. An essential part of the implementation of the 
dataflow algorithms is to use DFS post-order traversal.

Since it seems that flow.c is the place where we do our dataflow analysis,
I wonder why you decided to implement a new df.c unit. It seems to me
that it would be preferable to enhance the existing flow.c instead of
writing a different piece of code that mostly does the same.
