[Python] install issues with jemalloc

[asfimport]

just started seeing these on pandas builds in Travis CI: https://travis-ci.org/pandas-dev/pandas/jobs/345721382

    from pkg_resources import get_distribution, DistributionNotFound
    try:
        __version__ = get_distribution(__name__).version
    except DistributionNotFound:
       # package is not installed
       pass
    
    
>   from pyarrow.lib import cpu_count, set_cpu_count
E   ImportError: /home/travis/miniconda3/envs/pandas/lib/python2.7/site-packages/pyarrow/../../.././libjemalloc.so.2: cannot allocate memory in static TLS block

Wes McKinney / @wesm:
Well, this isn't good. The only thing that has changed is the jemalloc feedstock earlier today https://github.com/conda-forge/jemalloc-feedstock. We should be pinning to jemalloc 4.5.0.post, so we may need to update some things with the Arrow 0.8.0 builds

[asfimport]

Jeff Reback / @jreback:
pinned in pandas for now: pandas-dev/pandas#19888

[asfimport]

Uwe Korn / @xhochy:
This is still using pyarrow==0.4.1, we could also adjust these old package but I'd rather see pandas raise its minimal supported pyarrow version. I guess people using pyarrow are rather quick in updating.

[asfimport]

Wes McKinney / @wesm:
@jreback can you update to pyarrow 0.8.0?

[asfimport]

Jeff Reback / @jreback:
this particular build is using pyarrow 0.4 for compat tests
so pinning jemalloc is prob ok here
we r testing more recent builds and they r good
so closing this ok

[asfimport]

Wes McKinney / @wesm:
OK, we are not supporting old versions of pyarrow at all, so at your own risk
