I believe the court will allow the defendant to offer a reasonable restitution payment plan, since many people wouldn't be able to pay off a $100,000 judgement for criminal restitution immediately. I had a neighbor who was ordered to pay restitution for damages he caused when he crashed his car into a fence. His insurance company paid for some of the property damage, but he also destroyed a brand new $5000 plasma television sitting on the back porch.
The judge allowed him to make financial reparations on a monthly basis. The purpose of a writ of restitution isn't to drive the guilty party into bankruptcy, but to make the injured party whole again.
