Seen this on a family member's Mac. It ground to a halt in exactly the same way computers have for ages when too much virtual memory is being used. I think what's happened is that every single developer at Apple has SSDs on their work and home computers so they get wasteful with memory. When iPhoto needs 150% memory to update an index you're not even going to notice that with an SSD, but with an HDD the system can freeze up. This will eventually resolve itself once every computer has a SSD, but in the meantime the existing Macs with HDDs will be a mess.
