This sounds fine - anything related to SNAP can be disregarded at this point,
SNAP is an internal Microsoft gated checkin system which we used for 
submitting checkins and running all of the tests.

I don't see why we wouldn't want to always set IRONPYTHONPATH.  We did
at one point run our own tests both w/ and w/o the std lib but we stopped
doing that some time ago.
