It's done that way as a security measure against repo corruption.
Although I wonder if we could do connectivity check in background
instead (reports are stored in .git and picked up by git-status). The
same mechanism could be used for "git gc --auto". If the repo turns
out corrupted, the user may lose the last ~10 minutes of work, not
really bad for the speed trade off. This mode is not the default, of
course. The user has to be aware of the risk when choosing this route.
