# By default travis loads submodules serially, but we can load them in parallel
# if we install an updated git and use --jobs.  Some timing numbers:
#   serial: 257s
#   jobs=4: 182s (29s to install new git, 153s to run the downloads)
#   jobs=8: 179s (29s to install new git, 150s to run the downloads)
# We can't use --depth=1, though, because github doesn't have
# allowReachableSHA1InWant set.
#
# TODO(jefftk): once we're running on a server with git 2.8 or later we can have
#               --jobs without installing a new git.
