I don't see the problem. Typically, C extension modules don't have Python code that runs in their globals, so messing with a C extension's globals from the outside has no bad effect on Python code.

It happens, though -- for code whose performance is not important, e.g. initialization and "resetting" kind of stuff, a PyRun_String can be SO much more concise and handier than meticulous expansion of basically the same things into tens of lines of C code... since "messing from the outside" happens after initialization, and the use cases I can easily find are all specifically DURING initialization, it may be that this problem is too rare to worry about, but, I'm not so sure.
