Duplicate rows returned in View Query result after view compaction

Jenkins Ref Link:
http://qa.sc.couchbase.com/job/centos_x64--29_01--view_create_all-P1/150/consoleFull

Test to Reproduce:
./testrunner -i test.ini get-cbcollect-info=True,get-logs=True, -t view.createdeleteview.CreateDeleteViewTests.ddoc_ops_during_compaction,ddoc_ops=update,test_with_view=True,num_ddocs=4,num_views_per_ddoc=2,items=20000,fragmentation_value=40

Note: This issue is reproducible once in 3-4 times.

Steps to Reproduce:
1. Create bucket
2. Disable Auto Compaction
3. Load 20000 items
4. Create Views
5. Generate load until fragmentation value reached
6. Trigger View Compaction
7. Run View Queries
