How to ensure Xvfb is actually running?

[paulchill]

Hi,

I followed you're tutorial and all makes sense, however, is there a way to ensure Xvfb is running and also can exertion be loaded into this if election is built from chrome?

In the example, https://github.com/nisaacson/aws-lambda-xvfb/blob/master/example/bin/run.sh#L51 waits for the display to be available. Perhaps that was what you were after.
