-Previously if you opened different workspaces that had the same filesystem path
-(for example if you have /home/coder on two different machines that are both
-accessed through the same host) they would conflict with each other.  This

-The easiest way to test is to open files in the same workspace using both / and
-/vscode and make sure they are not interacting with each other.
