 Reducing the amount of printing done by the test cases themselves
 wouldn't have helped here, because the output that got buffered did
 not actually contain anything printed *by* the test case, but was just
 the atf-report "ticker" output *listing* each test case, its execution
 time, and outcome, for example:
 
     libbpfjit_opt_ld_abs_3: [0.009291s] Passed.
 
 Adding a new atf-report output format with one just line per test
 program rather than one per test case would probably help, but I don't
 think it would be a good trade-off - I grep console logs for the
 outcomes of individual test cases on a regular basis, but the present
 problem of a kernel panic getting attributed to the wrong test has
 only happened once.
