Can I automatically "preload" light-locker (or any screen locker) upon suspend?

When using XFCE in conjunction with light-locker (the default lock screen utility), it normally takes some seconds to resume from suspend as it loads up the light-locker prompt. However, I've found that if I let the prompt load up, but then close the lid without entering the password and let it enter suspend again, light-locker is almost instantly ready the next time I resume. Is there any way to do this automate this behavior when I close the lid of my laptop?
