I can do this. Should this be RC_1_33_0 or head?

Yes it does.

Here is the scenario. Library X uses something from library Y. Library Y is
changed. This triggers a rebuild on Library X. This in turn triggers a
re-build and re-test on Library X. At least that's way it looks like it
works to me. If I'm wrong about this, then why is so much time being
consumed on re-testing when none of the source code in Library X
(serialization) has changed ?

Well, its been this way for almost a year. And it has been inconvenient.
But its hard to justify characterization as an urgent emergency.
