We (a consultancy) seem to only use it when someone has some design/implementation questions and/or concerns. For example, I don't need someone watching me write code I'm comfortable writing... they should be busy producing as well. However, if I'm unsure about something, having someone look over my code and/or help code, is extremely useful. Code reviews is a different subject completely, and is "definitely" a great learning experience for everyone involved.
