Uwe L. Korn commented on ARROW-913:
-----------------------------------
Actually this should be the default behaviour. Linking should normally happen
with {{--as-needed}} thus all libraries from which no symbol is needed are
ignored by the linker. This only {{_jemalloc.so}} should link to
{{libjemalloc.so}}.
> [Python] Only link jemalloc to the Cython extension where it's needed

> If the user does not have jemalloc installed, it would be better to defer the
> library load failure until they try to use the jemalloc-based memory
> allocator. See e.g.
