> Version and repro info in the gist below.
> Not sure if I'm not understanding something from this [https://arrow.apache.org/blog/2019/02/05/python-string-memory-0.12/]
> but there seems to be memory accumulation when that is exacerbated with higher arity objects like strings and dates (not datetimes).
>  
> I was not able to reproduce the issue on MacOS. Downgrading to 0.14.1 seemed to "fix" or lessen the problem.
