Bug 566942 - Workaround some performance issues with CDO by enabling
DEPTH_INFINITE prefetch of CDO resources by default.
The org.eclipse.papyrus.cdo.core.resource.PapyrusCDOResourceImpl.ORG_ECLIPSE_PAPYRUS_LAZY_CDO_RESOURCE_LOADING
System property can be used to avoid this DEPTH_INFINITE prefetch.
