Running an LC app from the command line

Richard Gaskin has some advice, perhaps a year ago, on this list.  

I’m hoping to be trying that tonight.  

Well, maybe in the morning.

A signal 10 is a bus error.  If you are lucky, it is just accessing some GUI when there is none.  Just take that out.

Maybe you need to quit before the end of the startup handler, so preOpenStack never runs.  I’m hoping my notes from Richard’s email covers this.
