Passed hs-tier1-7, jdk-tier1-3. I started another run with latest
changes as CMS support (sans diagnostic flag change) has been added.

I think the change is good from a functionality POV, however I think we
can reduce the added boilerplate code (TaskTerminator with assignment
operators, etc.) a bit. Give me a few hours to try out something.
In the meantime I collected typos and formatting issues in
http://cr.openjdk.java.net/~tschatzl/8204947/webrev/ . Nothing
interesting to see there, but fixing up typos that I do not think are
worth listing one by one here again.
(It also changes the flag from experimental to diagnostic, but you
already did that).
