Signals now cause an event, and there's a way to continue until the
next signal. I can see this being used for detection of `int3`
although I'm not entirely sure as it may prove being too late to stop
abortion of process.
Since even a very basic ptrace can be nice to have, I thought I would split
the, perhaps rather big, ptrace project up in multiple PRs to make as few
changes as necessary in each. This PR contains the initial registry modifying
bits and only a very basic security measure. Letting this out to the community
should be good for spotting bugs and maybe getting some hype ;)
