[Python-Dev] importlib is now bootstrapped (and what that means)

Cython-generated C code would likely be more stable (and produce
compiler errors if it gets stale), whereas importlib.h needs to be
regenerated with byte code changes.

Having source code has the advantage that it becomes possible to
single-step through the import process in C debugger. Single-stepping
with pdb would, of course, be better than that, but I doubt it's
feasible.

In addition, there might be a performance gain with Cython over ceval.
