Is there a way to delete all the sources with their “child’s” and everything in the pipeline programmatically?

Something like

```auto
for x in GetSources():
    Delete(x)

```

?

My experience with PV5.8 is that this is not sufficient because it does not clean memory. I much prefer a

`ResetSession()`

What do you think?

I do prefer ResetSession, but it does much more than just deleting the sources.
