Don't share the workspace.
There is a *high* chance that you corrupt the workspace in a way that
could a) freeze a currently running instance of CSS, b) make
subsequently starting CSS instances immediately crash. I've been
rebuilding workspaces from scratch a number of times because of this.

One of the versions that allows silent workspace corruption is the
generic "SNS Basic EPICS" version that (in principle) is recommended for
non-SNS users. IMO, these versions are not improving the CSS reputation,
and should be fixed to lock the workspace.
