The first run is go test -race -cover without -v, so a green run prints
one line per package with its coverage. On failure, the top-level tests
named on "--- FAIL:" lines are rerun with -v in the packages that failed,
then the script exits 1 whatever the rerun's result. Rerunning only the
failed tests keeps a red build log far below the 2 MiB at which the
Docker build cuts it off (issue 414). The timeout, -p 4 -parallel 8 and
their header comment are unchanged.
