Why would you do that unless it's a hotfix or something really critical? Are the costs negligible?

So, it depends. When I was at FB, we had one person in Europe (me), one in SF and one in Asia.

Organising the diffs in this way made it much, much easier to collaborate.

Given how much FB has grown since then, I suspect this would be even easier, and this is how the numbers noted above are what they are.
