> When stored fields are configured with {{BEST_COMPRESSION}}, we rely on
> garbage collection to reclaim Deflater/Inflater instances. However these
> classes use little JVM memory but may use significant native memory, so if
> may happen that the OS runs out of native memory before the JVM collects
> these unreachable Deflater/Inflater instances. We should look into reclaiming
> native memory more aggressively.
