[jboss-dev] VFS Temp Reuse (JBAS-6715)

Only client side top root is kept,
all other (sub)roots are cleaned up at undeploy,
and new DeploymentContext (+ roots) are created an (re)deploy.

Only top root should get reused - the client side,
all other should be re-created.

I need to check this.

That's expected.

It's parent context was reset,
hence new contexts should be created for nested zips.
But they shouldn't reuse any temp info,
either is shouldn't exist --> cleanup by undeploy,
if we somehow missed that, it shouldn't be valid.
