------------------------------------------------

[~anastas]
My UT was very simple. I selected the testCompaction1Bucket or any such test case. I just
added some keyvalues but ensured that there are 50 cols in each row. 
I called flattening manually and then checked the count of cells in that flattened segment.
I think you will get that issue pretty directly. I don't have that UT now as i reverted my
changes. 
Let me know if you still need them I can paste them here. Thank you.
