[compiz] switch metacity->compiz (compiz ignores its own settings)

[dragoran]

I have configured compiz to use 1 workspace and 4 viewports and metacity 
to use 4 workspaces.
When I start compiz while metacity was running it uses 4 workspaces and 
4 viewports (ignoring the gconf settings).
When I restart X so that compiz is started before metacity this does not 
happen (it uses what its configured for).
bug or feature?
if feature can it be disabled?
switching metacity->compiz without X restart is no longer possible with 
this..
