Currently, git doesn't seem to be very good at handling two concurrent
invocations of git fetch (or git fetch and git pull). This is a
problem because it is common for git clients to run git fetch
periodically in the background.

I think it's a really weird idea which makes a disservice both to human
git users and git servers. IMO clients doing this should be fixed to
avoid such behavior, at least by default.
