Enables
jemallocas global allocator for Linux builds. This should reduce memory fragmentation and reclaim unused memory quicker, which is expected to lower Relay's overall memory footprint.Relay's processing profile frequently moves memory between threads and also spawns threads on the fly. To allow the allocator to reclaim this memory efficiently, we also enable the
background_threadsoption. See jemalloc/jemalloc#1128 (comment) for a mention of this.See #344
See #1817
