Isn't it just syncing and verifying the chain?

Does it also do this if you pull the internet connection?

The latter part of synchronization is CPU bound if your internet connection is fast and you have a good peer to pull from.  This means that it'll use whatever cpu is available until its finished. If it artificially used less cpu then it would just take longer to finish.

(Not to say that there might not be bugs too— but just the uses lots of cpu during sync is not itself an indication of a bug)

Try command line option -par=1 to limit to one core (or whatever number you want) only.
