Build Identifier: 2.0.0 2.0.1

Xtext uses EMFBasedPersister to keep the Index during a restart of eclipse.

This leads to following problem:

(1) We have a workspace with 2+ projects
(2) on start EMFBasedPersister loads the index using an xmiresource.
    the reference to the xmireasourse with all its contents is kept through
	ResourceDescriptionsData
(3) starting a clean build on one projects leads to a replacement
    of the corresponding resourcedescriptions in  
	ResourceDescriptionsData.addDescription(URI, IResourceDescription)
(4) but the old ones stay still alive cause there is still a reference
    from the other resourcesecriptions to the xmiresource
(5) => if the project is clean is very very big and the other
    very small then this will lead to a nearly doubling of consumed memory


Reproducible: Always
