PS2:
Thank you for the write up -- I must admit I haven't read it yet to digest 
everything, but I'm planning to do so when I can allocate more time for this.

The only feedback at this point from my side is that the test is still failing 
even with this fix:

src/kudu/tablet/compaction-test.cc:910: Failure

constraints"
