12c: Cursor wait with In-Memory and Parallel queries running

I think it is interesting that the MOS article "Significant 'Cursor: Pin S Wait On X' Waits When Using In-memory Column Store and Parallel Query" via note ID 1910787.1 is saying there is a serious bug with 12.1.0.2 where you try to query data in parallel with In-Memory options enabled.  I would say the whole point of 12c is the In-Memory store, but remember that In-Memory is an option that came after 12c was introduced so really it is not that surprising that we will start seeing some of these one-off bugs start rattling out of early adopter systems!
