Hi, I notice you committed https://github.com/polyml/polyml/commit/891e8122dcca36f9c2e9eea5a3eca7cf5de9.... However, as it stands, on armel the calls do not raise an exception like https://github.com/polyml/polyml/pull/16, which could be misleading for the user, as as far as they are aware setting the mode has succeeded (and getting the mode may return the new mode). Also, unless I?m mistaken, you have effectively just completely disabled that test on every platform, as any failure will be caught.

Regards, James
