// Implementation of Reactor functions that are "emulated" - that is,
// implemented either in terms of Reactor code, or make use of
// rr::Call to C functions. These are typically slower than implementing
// in terms of direct calls to the JIT backend; however, provide a good
// starting point for implementing a new backend, or for when adding
// functionality to an existing backend is non-trivial.
