In the linux kernel this comes from: state = READ_ONCE(p->__state); i = state ? ffz(~state) + 1 : 0; psinfo->pr_sname = (i > 5) ? '.' : "RSDTZW"[i];

So we replicate that here. From proc_pid_stats(5) R = Running S = Sleeping on uninterrutible wait D = Waiting on uninterruptable disk sleep T = Tracing stop Z = Zombie W = Paging

pr_flags is left as 0. The values (in linux) are specific to the kernel. We recover them from the proc filesystem but don't put them in ProcessInfo because it would really become very linux specific and the utility here seems pretty dubious
