server.py continues to run when JupyterLab is closed

[mandieq]

Per discussions with @jacobtomlinson I've seen the following behaviour...

Each time I run JupyterLab and then shutdown it down cleanly from the browser window - the server.py process continues to run in the background. And if I start JL anew, I get another incarnation of server.py. So this is what I see after I've started and stopped JL 3 times:

My expectation would be that this process would finish with JupyterLab.

I'm running on an POWER9 server, RHEL7.6, jupyterlab 1.2.4 and jupyterlab-nvdashboard 0.1.11. Let me know if I can provide any more info.

I'm seeing something similar, an excess of these processes after JupyterLab sessions have shut down. Is it possible to have a configurable that would shut the process down after some amount of inactivity?
