Review comment:
       This is why I was interested in figuring out whether pcollection is not 
streaming, so that windowing wouldn't matter. I don't fully understand the 
code, but the comment to Reify suggests that wrapping is also needed outside 
the visualization ('When it detects one, it puts the element into the correct 
window then emits the value to downstream transforms').
   
   It seems nice to have this just depend on the flag, but are we sure it would 
work pcollections with non-trivial windowing? I also can imagine a case where 
ib.collect is called with `include_window_info=False` at first and then with 
`include_window_info=True`, which probably would result in an error.

> Currently InteractiveRunner wraps every record of the cached PCollection into 
> WindowedValue. There is 2 problems about this:
> 1) The windowing information is unnecessary for the batch-mode runs 
> (everything is in the same global window).
> 2) Since the cache is stored as text, we pickle the WindowedValue, which adds 
> ~500 bytes of data to every record (e.g. a cache of just 1000000 integers 
> would take ~500MB instead of ~4MB).
> These issues significantly slow down the interactive runs for data with lots 
> of small rows.
