...to reduce file locking on Windows caused by clangbackend's parse/reparse jobs. Considering inactive application state should help for external VCS operations, e.g. on the command line. However, activating Qt Creator while such a VCS operation runs might still lead to undesired behavior, but this should be the less common case. VCS operations started from within Qt Creator should see less locking conflicts as we know when they start and finish. However, we just avoid starting new jobs - there might be still jobs running. Pending or new jobs will be started once Qt Creator is activated again and all VCS operations finished.
