Subject: [PATCH] Added "ps-less process tree way"

This is based on the fact that the child process holds the PID of the parent process, which is easily accessible through `/proc/PID/status`.

Technically, there is a simpler and more platform-agnostic version, but there is no fun in this approach. We can still add it for posterity.

```
:!kill -9 $PPID
```
