Gets in the way with other CLI git usage

[jrudess]

After a long time of using this in my tmux status, one of the major issues is that on a fast machine with local disk repos that aren't gigantic, I see no issues. On a work machine, with repo living on an NFS disk, and the repo is gigantic, the git calls made by the status line can actually take an incredibly long time to complete, and the calls create a lock file. Then all CLI git access is blocked or fails until the status-job finishes. In that environment, I've removed this tmux-plugin, and instead prefer to glance at the git info from within vim via something like gitgutter, although it doesn't have info about number of available remote commits, etc.
