You are aware that layers can be nested?

  The implication of this is that a sublayer (run in a subprocess)
  either must start from scratch and reconstruct the fixture
  built in the superlayer (potentially expensive) or
  must access the resources inherited from the forking process.

The latter (accessing resources inherited from the forking process)
is very brittle. I had to give it up in a different context.
