Cannot start more than one browser processus since CEF 121

[apique13]

Describe the bug
Cannot start more than one browser processus since CEF 121 (cefsharp/CefSharp#4668)
I understood it is because of the CefSettings.root_cache_path parameter, but what is the good solution to manage it ?
The only workaround possible should be to define a random root_cache_path for each instance, but it is a bit dirty.

To Reproduce
Launch run.bat to start the demo browser.
Launch it twice, The second browser will hang.

Expected behavior
A clear and concise description of what you expected to happen and what happened instead.

This is actually expected behaviour, each browser process needs its own root cache folder now, use something like this:

CefSettings settings = new CefSettings();
Path tmpDir = Files.createTempDirectory("dc-");
tmpDir.toFile().deleteOnExit();
settings.root_cache_path = tmpDir.toString();
