I get your point but let's just say this is something I've been tasked with. Apparently, the _javascript_ team discovered that too much time is being spent in free, or something like that. My goal is to plug in jemalloc and then let the _javascript_ team profile again.
Why not using a custom allocator for _javascript_ only ? The _javascript_ engine should be design with memory allocation hook, so you can plug any allocator you want just for this specific part.
