Public bug reported:

Its possible for new windows to be stacked above panels if they are
created just after an override redirect window is created and just after
the window before it was restacked to the correct position (race
condition). In this case, serverPrev will be set to the window it should
be stacked above (correct) and the window will request to restack above
the same window. In reality, the window is still at the top of the stack
and not just above serverPrev because it was never restacked yet.

Steps to reproduce at least for me:

1. Log in to unity-2d or gnome-classic
2. kill unity-2d-shell (so just the panel remains)
3. Open nautilus and repeatedly hit Ctrl-N to create a new window really quickly
4. Windows will eventually go above the panel
