Er, except we have no gc at the moment :-D so even things like the
WebRequest object will just linger forever in the Site's vobjectTable
until the process is restarted.
I went ahead and re-added transient views, essentially by moving the
createView() logic from the ViewFactory to the ViewImplementation, where
it can be overridden. But that means I'll still be leaking WebRequest
objects. Is it as simple as adding a Site.releaseVobject(vw) method (to
delete vw from the vobjectTable, therefore allowing the refcount to
eventually reach 0)? Or am I missing some implications? I know later on
we want to have a smarter, proper gc, but for the simple case...
best,
Lalo Martins
