I think the most obvious place to document compiz gotchas is in the 
compiz tree itself.

How about a GOTCHAS.whatever in the root of the tree.  Some sort of 
markup used in the file, referenced from README, and if need be, we 
could get the file formatted and uploaded somewhere useful on every 
commit, just to make sure we don't get a stagnant wiki page that is out 
of sync with the code.

How about that?
