One feature that we miss from jemalloc is junk filling. When enabled, all allocated bytes are set to the value 0xA5. The number isn't important, but it can be a useful debugging tool when looking at memory dumps as it indicates an area that has been allocated, but hasn't been initialized to anything.
I believe mimalloc doesn't initialize the memory to any value, instead just returning whatever is pre-existing at that address. It would be great if mimalloc had this capability.
