# travis changes on 2017.06.21 appear to have broken pypy, causing attemtped
# downloads of "-.tar.bz2" (resulting in 'bzip2: (stdin) is not a bzip2 file.')
# (same changes MIGHT also have gotten a version of CPython 3.6 exhibiting
# https://bugs.python.org/issue29167; at least, that bug is definitely
# appearing.)
# Pinning to previous travis image for now.
