cmake is now filled with 'sudo' but with sudo timeout this should be
fine.

Only reason for it to be big is if you want super large zero padding

This was a necessary addition since the syscall() function
used over 2 KiB of stack space.

Kernel: Userspace signal handlers are now called one at a time

I added a syscall for telling the kernel when signal execution has
finished. We should send a random hash or id to the signal trampoline
that we would include in the syscall, so validity of signal exit can
be confirmed.
