Hi Kevin - it's a legitimate question, thinking about what happens when the process is not doing anything is important. The obvious answer is to disable the screen lock completely, and if you look in the infrastructure documentation you'll see it's a key recommendation of ours, along with fixing the screen resolution, disabling font smoothing etc.
Login Agent is another option - it has the ability to unlock the screen.
The least elegant solution is to keep the lock away by keeping the desktop active. For example, you can attach to explorer.exe and spy parts of the desktop. I've done this in the past to click the Windows start button to make the menu pop up every 30 seconds while waiting for queue items. It's crude but effective.
