The first time a subinterpreter attempts to import a module without proper subinterpreter support, an ImportError is raised (which is correct). However, subsequent imports of the same module succeed!
Using readline as an example, since it's currently single-phase init:
>>> from _xxsubinterpreters import create, run_string
>>> s = "import readline; print(readline)"
>>> interp = create()
>>> run_string(interp, s)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
_xxsubinterpreters.RunFailedError: <class 'ImportError'>: module readline does not support loading in subinterpreters
>>> run_string(interp, s)
<module 'readline'>
