Prevent application from restarting computer

[Curt@invincea]

In my case a sandboxed app were still be able to perform a reboot and it was not malware. A normal installer that I've ran sandboxed where I forgot the tick off the mark "reboot now" after sandboxed installation.

What is this app?

This seems ...inconsistent with my own experiences. What exactly counts as "valid reboot command" and why is it permitted?
