Whenever
we check magics, we can now try those first, and more likely than not,
discard the candidate right away and move on to the next one (whether
it is by exhaustive search or randomness). It's actually a significant
speedup. But occasionally, we simply cannot find a magic for a given group; either
there is none, or we didn't have enough time to scan through enough of the
64-bit space.
