Connection pooling and relationship between EF and ADO isn't explained well in the documentation (AFAIK). I've added it to clarify it. Given the authority of the doc, it should clearly explain it.

@roji thanks for your feedback. I've tweaked it accordingly. Please let me know your advice.

Thanks @azarboon. I've pushed a commit proposing some tweaks; we need to also keep in mind that EF supports non-relational providers as well, where ADO.NET doesn't play any role (and in fact, no pooling is done or needed, since there's no persistent connection).

Let me know if this looks OK to you.
