> [----------] 2 tests from Jemalloc
> [ RUN      ] Jemalloc.SetDirtyPageDecayMillis
> [       OK ] Jemalloc.SetDirtyPageDecayMillis (0 ms)
> [ RUN      ] Jemalloc.GetAllocationStats
> /home/antoine/arrow/dev/cpp/src/arrow/memory_pool_test.cc:218: Failure
> The difference between metadata0 and 3000000 is 2962256, which exceeds 1000000, where
> metadata0 evaluates to 5962256,
> 3000000 evaluates to 3000000, and
> 1000000 evaluates to 1000000.
> [  FAILED  ] Jemalloc.GetAllocationStats (0 ms)
> [----------] 2 tests from Jemalloc (0 ms total)
> {code}
> It looks like those checks should be relaxed to allow for more context-dependent behaviour.
