My understanding is that the system restore checkpoints happen every five seconds. They hold a lock, which seems reasonable. The problem is that for some reason on this machine the checkpoint process was taking a really long time. I also don't understand why it was taking so long. It normally doesn't. Something went terribly wrong. > and if designed nicely, quite fast. Yep, should be. But it wasn't. If everything worked as it should then I'd never get to write any blog posts!
