> DockerConnectionManager.getInstance() will end up calling reloadConnections if the singleton has not yet been created (likely when a user opens the perspective for the first time). The call exists in various createControl() methods so the reloading of connections could take place under the UI thread.
> We should guard against this by having the logic execute under a background job that populates the Explorer view as it completes.
