@rafaeldtinoco WDYT?

[rafaeldtinoco]

LGTM. Needs a better reasoning and a PR changing the types before this can be merged. Im putting a -1 for now until both are satisfied. Request my review in the types change, please. I'll merge and you can rebase this and change types dependency to that commit.

@rafaeldtinoco I probably need your opinion on the following question:
Should the query time be part of the info objects, or be part of an enveloping type to the info objects?
In my opinion it is easier to manage as part of the info object, but I am not sure that the timestamp is an info of the process in a way that justify this coupling.
We can create a generic TimeRelevantInfo type, that has information and timestamp in it, and return it instead of the process and thread info objects.
WDYT?

I think I prefer this idea better Alon, if you also think that.

[rafaeldtinoco]

We agreed the location of Timestamp will be a struct called TimeRelevantInfo instead of duplicates under other Info structs.
