This applies to stage2 where we make use of the cache system to work out if we need to relink objects when performing incremental updates. When the process is restarted however, while in principle the idea is to carry on where we left off by reparsing the prelinked binary from file, the required machinery is not there yet, and therefore we always fully relink upon restart.
