Subject: Anti-concurrential git-status for prompt update... When a .git folder
 contains to many blobs and takes too long time to get the status, instead of
 hanging up every shell, just let one of these (the first, of course) getting
 the current git status, the others will take the previous one, else a
 'running' color status.
