Run it in a VM instance that can be snapshotted/checkpointed, so that any reboot turns into "suspend and resume from checkpoint"? Or are there any pitfalls to just doing that?

Yes that can help, but VMs are still either Linux or OSX or Windows, and they all require security or other updates that will eventually need to reboot the system. Also the processors are different.
