The call to _PyInterpreterState_LookUpID() may generate a Python exception but it is not explicitly cleared on error and no indicator is returned to signal failure. This can lead to a "a function returned a result with an error set" fatal error, and does in fact do so in a case I encountered in Modules/_xxsubinterpreters.c:channel_destroy().
