some small progress on the port to Unix

Been pretty busy at work lately, prepairing for year end. And last weekend I wasn't feeling well. But finally things are coming together again and I was able to spend a short time this AM IST (Indian Standard Time) working on the Unix port of CompStrm-1.

I ran into a bug that was a bit of an anoyance--the stop command, when entered in the lineclient, failed to completely shut down the server. So I focused on that.

I found that by reorganizing lineserver.py, the takedown completed. And that's very handy when doing a lot of test/edit/test.

Now there are more significant bugs remaining--I can't even do a tki dir command from the client. But at least I'm making progress.
