/* This returns the address of the code object
   as the identifier.  The mapping from identifiers to string
   representations of the code object is done elsewhere, namely:

   * If the code object dies while vmprof is enabled,
     PyCode_Type.tp_dealloc will emit it.  (We don't handle nicely
     for now the case where several code objects are created and die
     at the same memory address.)

   * When _vmprof.disable() is called, then we look around the
     process for code objects and emit all the ones that we can
     find (which we hope is very close to 100% of them).
