Jorge Leitão updated ARROW-15741:
---------------------------------
    Description: 
The C stream interface has the method `get_next` that mutates the producer side.

We do not mention whether there is some kind of thread safety associated to 
such interface. For example, can the interface be shared between two threads 
and both call get_next at the same time?
