The 'nproc' fallback will potentially cause twice #CPUs processes to be
active, since sphinx will run in parallel with everything else.
Is this result with "-j auto", and if so with which computer? If the
speedup is only 2x as it seems to be from the "time" above, I'd rather
have "-j 2" only so that sphinx doesn't risk killing the machine...
