> On ARROW-6437 (https://github.com/apache/arrow/pull/7928) we saw occasional
> "File exists" errors on jemalloc_ep on macOS. Googling the error message led
> back to ARROW-739 (https://github.com/apache/arrow/pull/456), which fixed
> this before by forcing install with {{-j1}}. ARROW-3492 later made it so
> jemalloc would build (but not install) in parallel. Then ARROW-3539
> (https://github.com/apache/arrow/pull/2779) was addressing a problem with
> that change and, along with fixing the build parallelization issue,
> unfortunately reverted the original {{make -j1 install}} fix.
