yes, you need a <finally> clause, which makes rollback that much harder.

SmartFrog's life is easier as there all components have an sfTerminate() 
operation that is called for them to clean up (or do a best-effort 
cleanup, let's be honest) at the end of their lifecycle. So it's easier 
to rollback state. when a sequence fails you terminate everything that 
is already running/deployed, then create new instances and try again, 
after an appropriate wait.

we dont have the same in ant...
