Hi,
So I created this generic program because I was seeing a leak in BS_Data
and wanted to ensure it wasn't StdLib and also wanted to ensure it wasn't
the shell (the same occurs if you just keep booting this file over and over
- using OVMF in VirtualBox because easier) and you'lll see a leak. About
every 5th time you'll see BS_Data increase.
Important Note: you'll have to bump up your PcdUefiLibMaxPrintBufferSize
from 320 to something larger (I used 2048).
