/* 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).
