Hmm, so I've tried to use my version of awk on other machine and vice
versa and it didn't make any difference. So this is independent on the
awk version it seems. So I've tried to strace /usr/bin/time and
wait4(-1, [{WIFEXITED(s) && WEXITSTATUS(s) == 0}], 0, {ru_utime={0, 0}, ru_stime={0, 688438}, ...}) = 9128
so the kernel indeed reports 0 user time for some reason. Note I
was testing with 4.7 and right now with 4.8.0-rc3 kernel (no local
modifications). The other machine which reports non-0 utime is 3.12
SLES kernel. Maybe I am hitting some accounting bug. At first I was
suspecting CONFIG_NO_HZ_FULL because that is the main difference between
my and the other machine but then I've noticed that the tests I was
doing in kvm have this disabled too.. so it must be something else.
Weird...
