> We spend a fair amount of time in the allocator. While we could spend some 
> time trying to use arenas more, it's also worth considering switching 
> allocators. I ran a few quick tests with jemalloc 4.1 and it seems like it 
> might be better than the version of tcmalloc that we use (and has much more 
> active development)
