[Seaside] updating children components

	Seaside components have a #children method whose result must not vary
in a single rendering pass, but it might be called several times. Is 
there a way to know
when the rendering pass starts and ends ?

In fact we have trees of domain objects that can be seen by several 
users at the
same time, and we want to manage udpating using an observer pattern, as 
tree's shape can change (and therefore the component tree too). So we 
want the
children to change only after each rendering pass.

	Thanks in advance,

On a sidenote, maybe the children method could be called once per 
rendering pass ?
