  This seems to indicate that the test harness itself is taking 87% of
the execution time — no?

  There's no comment on the function TreeTester.reordered, but it seems
like that class is related to checking consistency of the tree. Part of
the reason of having a test suite is so that one can write multiple
tests...e.g. some for tree consistency, others for performance. Unless
the TreeTester is used within GTG every time a tree is created, maybe it
is more realistic to do test_speed() without consistency checking?
