{-
This simple graph tests the topological sort of the unit generator
graph, it ought only to use a minimal number of interconnect buffers.

The below 369 node graph works with 'scsynth -u 57110 -w 2'.

(Note that graphs loaded from disk during startup will grow the number
of interconnect buffers, so to test this we must delete all graphs that
would otherwise be loaded.)
