About half of the failures in the logs seem to coincide with rsc.io server outages that cause other tests to fail.

Otherwise, in order to make progress debugging we will need more output from go get -u. I will port the test to a script and add the -x flag to get more detail about what the spuriously-succeeding command is doing.
