One for the PTRACE_SEIZE thingy, one for the "mechanism to prevent a process from resuming" and maybe (depending on how involved it gets) one for refactoring the /proc/status parser.

I'm okay with that, I'm still in the 'experiment and see what happens phase' when it comes to preventing continue.

How does this proposal sound:

* SEIZE + Parsing Proc Status
* GDB Server changes to prevent resumption
* Move the Proc Status (not stat) code to the HOST class

For #3, I think it's got some loose scope around if it should replace proc stat or be in addition to it. The biggest complexity here is we're adding information into qProcessInfo that isn't exclusively about the process but now about how we're interacting with the process. So I think tackling that as it's own step makes sense.
