Public bug reported:
WindowStateStorage uses QtConcurrent::run with the default QThreadPool
to write in the SQLite database. But the functions passed are not
guaranteed to be executed if there is no available thread in the pool.
Steps to reproduce reliably:
1. Use a computer (or a VM) with only one CPU core
2. Start any app
3. Resize the app window
4. Close the app
5. Restart the same app
Expected result:
After the app is restarted the window size is back to the size given by the
user.
Current result:
After the app is restarted the window size is the default size.
However if unity8 is restarted the geometry is then correctly saved to
DB and correctly restored after the app is launched.
