> Followup to ARROW-6910. When loading the R package after that patch merged, I
> get this new message:
> {code}
> $ R
> > library(arrow)
> <jemalloc>: option background_thread currently supports pthread only
> {code}
> https://github.com/jemalloc/jemalloc/blob/3d84bd57f4954a17059bd31330ec87d3c1876411/src/background_thread.c#L884-L887
> is where the message comes from. Tracing that further,
> {{have_background_thread}} comes from
> https://github.com/jemalloc/jemalloc/blob/21cfe59ff7b10a61dabe26cd3dbfb7a255e1f5e8/include/jemalloc/internal/jemalloc_preamble.h.in#L205-L211,
> which gets set in {{configure.ac}} here:
> https://github.com/jemalloc/jemalloc/blob/d2dddfb82aac9f2212922eb90324e84790704bfe/configure.ac#L2155-L2157
> In sum, on my system, that flag doesn't get set, so
> {{have_background_thread}} is false, and when that is false and the
> {{background_thread}} option is true, I get that message printed. And I do
> not want to see that message.
