Split out readRelocTargets() to a separate method, which is called in parallel. This reduced the performance drop quite a bit, now the difference is much smaller. In this test round, the fastest run for the original version was 395 ms, after this patch the fastest run was 401 ms. So in this case, the slowdown is around 2% which hopefully is more acceptable.
