Bug 316468

Suppose you set focus stealing prevention to "Medium". Now you launch Chromium, open a website which should trigger a KWallet window asking for password. While the site is loading, you open a Yakuake window and start typing  a command. As you type, the KWallet window finally opens and you end up typing end of your command into password field.
That sucks, you may think and raise focus stealing prevention level to "High". Now, this scenario doesn't appear and you easily get your command executed. But, when you launch e.g. Systemsettings, you find that its window (which you yourself just asked to appear!) appears behind already present Chromium window. What's that? You weren't typing anything, but the newly-opened window, which the user _explicitely_ asked to appear still doesn't appear in front of the user.


Reproducible: Always

Steps to Reproduce:
0. Set "System Settings->Window Behavior->Window Behavior->Focus stealing prevension"  to "Medium" or smaller.
1. Open a terminal, e.g. Konsole or Yakuake
2. Type "sleep 2; kdesudo true" in the terminal and press Enter
3. Open a new tab in the terminal (Ctrl+Shift+N) within 2 seconds and start typing
4. See that once kdesudo appears, your command ending goes to password field instead of terminal
5. Now set "System Settings->Window Behavior->Window Behavior->Focus stealing prevension"  to "High"
6. Launch an app, e.g. a browser, maximize its window.
7. Now launch another app, e.g. Dolphin
8. See Dolphin hiding behind the window appeared in step 6.
Actual Results:  
Medium and High focus stealing prevention levels are too far from each other in their effects, both unsatisfactory.

Expected Results:  
There should be some level which would allow newly opened windows get focus IFF the user hasn't been typing anything for at least 1 second.

I'm using KDE 4.8.5 in Ubuntu Precise, but I guess nothing has changed since that time.
