Marcin S 8bf5a1c0b3 PVF: ensure job processes are cleaned up, add tests (#2643)
Fixes a potential memory leak.

`PR_SET_PDEATHSIG` is used to terminate children when the parent dies.
Note that this is subject to a race. There seems to be a raceless
alternative [here](https://stackoverflow.com/a/42498370/6085242), but
the concern is small enough that a bit more complexity doesn't seem
worth it. Left a bit more info in the code comment.
