I was thinking it is focus stealing prevention gone astray as well
in my case (Natty, unity-2d PPA) I trigger this behaviour when:
* I click a link in chromium and immediately press alt+tab to bring up the terminal in order to see something logged
* I am writing an email (thunderbird) and press alt+tab to see something in another window
* I am editing some text somewhere - pidgin, libreoffice, chromium or firefox url bar - and I press alt+tab
some means of configuring / disabling focus stealing prevention would be great IMO
