That's a different thing entirely from the purpose of my series. My
series is designed to allow EFI applications to be *linked* with
sandbox and run just like normal C code, with a full unified stack
I think this is a very useful feature separate from running EFI
binaries in user space.

I don't know what it entails but Heinrich says there is a memory
alignment problem to resolve. I was able to repeat his FAT failure but
adding his patch and a few other tweaks.
I'm happy to look at this once we have basic sandbox support
available, but if Heinrich wants to take a look, he is welcome to.
