CPU and memory load generation scripts

I was asked today how to generate CPU and memory load on a Windows server. I remembered from my VMware ESX training a VBScript which generated load on the CPU, but had never seen a script to stress memory. So I hacked together a VBScript which has an infinite loop which just keeps creating large arrays and filling them with data. Eventually the script bombs with an out of memory error, just what I was after!
Feel free to use the CPU loading script (thanks to VMware and Xtravirt) and memory loading script but please do NOT use them on production systems!
