Made exec syscall relative using app name
My plan is to implement a mobile-OS-like sandboxing using manifests
and permission middlewares. Let's see if I can manage to do this
without sacrificing too much performance.
I'm also wondering whether I should implement open/close syscalls
which would result in a cleaner block/unblock mechanism. I need to
think. Hmmm.. Naa
