  Re-enable tests, they were failing since gc.collect() clears the various freelists.
  They still remain fragile.

  For example, a call to assertEqual currently does not make any allocation
  (which surprised me at first).
  But this can change when gc.collect also deletes the numerous "zombie frames"
  attached to each function.
