Me too.

FWIW, here is a benchmark generator script, which just adds tup to this

  http://retropaganda.info/~bohan/work/sf/psycle/branches/bohan/wonderbuild/benchmarks/gen-bench

You run it as

  $ ./gen-bench medium 50 100 15 5
  $ cd medium
  $ tup init; tup monitor
  $ time tup upd -j3            # full build
  $ touch lib_20/class_20.hpp
  $ time tup upd -j3            # incremental build
  $ time tup upd                # do-nothing rebuild
