I have a customer that has encountered what I believe to be
https://issues.apache.org/jira/browse/ARROW-9114

They are running Windows.  They receive an illegal instruction exception on
pyarrow.parquet.read_table.  Their processor (i5-3470) does not support
BMI2.

The customer is using the pypi distribution (installed with pip).  The fix
for ARROW-9114 appears to have been a change made to snappy-feedstock which
patches snappy before building it.  However, I think this only applies to
the conda distribution.

Will there be a corresponding change made to the pypi distribution of
pyarrow?  Or is this something the pypi distribution should not have
exhibited anyways?
