SystemMonitor: Show PPID, PGID, SID
With this information, it's a bit easier to intuit the current 'process tree'.
If you're reading this, can I convince you to implement a nice process tree for
SystemMonitor? It could be via PPID (unbounded depth), or SID+PGID (depth 3).
Or something else entirely :D
