This happens with larger models after re-instantiation when the instance editor is open. It is caused by use of the EMF transactional model editor, which manages a resource set that is automatically updated if models change. Using this editor is a leftover from early OSATE2 before the switch to Xtext. It can be removed.

Note: check that the instance editor resource set doesn't keep stale resources loaded.

It is the workspace synchronizer that blocks the UI.
