In reply to @.bobbbob "what are the advantages": advantage: you don't use the
Nim allocator (one thing that come in my mind is multithreading because the nim
allocator has bugs here and there that makes it harder than it should), you can
override malloc with another allocator of your choice like mimalloc
disadvantage: you don't use the Nim allocator, if you dont override malloc this
means you have to make a syscall for every allocation your program does which
can significantly slow it down because nim preallocate memory and reuse it to
avoid those slowdowns
