This prevents multiple simultaneous runs of the analyzer from stomping over each other (e.g. multiple runs of 'update-packages'). Certain long-lived commands (like analyze, run, logs) are exempted once they've done enough work to be safe from most stomping action. This still doesn't make us entirely safe from craziness, e.g. if you're half way through an 'update-packages' run and you call 'git pull', who knows what state you'll end up in. But there's only so much one can do. Fixes https://github.com/flutter/flutter/issues/2762
