I have 4 gigs of RAM in my iMac. When I open programs my iStat's show that the memory utilization grows with each application opened. But as I close those applications the memory utilization doesn't appear to drop off, it's stays pretty much maxed out even if I close all of my applications.
Is it iStat's mis-reportig utilization or do I have some oddball memory leak?

This sounds normal. It doesn't indicate a memory leak — that's just how OS X manages memory.

To answer your question, though, the only way to clear your memory is to reboot. Or to physically remove it and shake it like an Etch-a-sketch.

Free memory is wasted memory.
Don't waste memory.

Unused RAM is a terrible thing to waste.

Indeed. People, this isn't OS 9. You don't want free memory. Having a huge chunk of inactive memory is just fine (because it means stuff will already be there when it's needed next time). No reason to panic.
What you want is no page-outs. If you see a lot of those it's time to get more memory.
Again, this isn't OS 9. Let the OS handle memory management for you. It's better at it than you are.
