Bogdan's code changes appears to have fixed my problems with long delays switching between xml documents. I looked at the code changes he checked in, and identified two jars affected in this build: http://www.eclipse.org/downloads/dow...-x86_64.tar.gz
So I swapped in these two jars:
org.eclipse.e4.ui.services_0.10.2.v20121107-162442.jar
org.eclipse.e4.ui.bindings_0.10.2.v20121107-162442.jar
and updated the bundles.info to point to the new jars, and no more waiting!
Thought others might want to know...

Just tested that and seems better when switching to XML editors.
Thanks John.
