   I think it'd be possible & reasonable to (add a mode where) over-allocate by 64 bytes and then use the aligned subset of the buffer. That's what Arrow C++ actually does when using libc malloc.
   
   I'd have to look more deeply into Netty to see what it does though.
   
   Was your Java application using the Netty allocator or the "unsafe" allocator?
