Ahem, no: the lazy mode only loads (and therefore compiles) components 
the first time they are looked up in the service manager. That means 
that currently you have to "touch" the sitemap in order for classes to 
be reloaded.

But the actual purpose of the lazy mode is not only fast startup time, 
but also fast *reload* time: the idea is that when a source file is 
changed, Cocoon is restarted in the same way as a ?cocoon-reload=true, 
therefore recompiling everything that needs to be recompiled and 
garbaging all instances of the previous versions of recompiled classes.

But that reloading isn't there yet.

Thank you, that's much clearer than my explanation (though I meant the same ;-)
