There was a problem hiding this comment.
_testsinglephase is unusable in subinterpreters.

We don't need to enable GIL for the
PyModExport_function, which is supposed to do as little as possible before returning a static array.Py_MOD_GIL_USEDcan be handled at module creation time, without enabling it transiently first.The main difference from
PyModuleDef(i.e.import.c'simport_run_extension) is that hePy_mod_createfunction runs without the GIL enabled transiently. (It does run with GIL enabled permanently ifPy_MOD_GIL_USEDis specified -- same as thePy_mod_execfunction, which always runs after the EnableGILTransient block.)Also, if
Py_mod_createmakes a non-module object,Py_mod_gilis honored.@colesbury, does this look OK?
