title: using memfd_create and fexecve to run ELF from memory
body: <p>I know other people have done it in different languages but I cannot find a C code example at all, the most common was in Perl and it was really confusing because I don't know Perl
  and I just want to load a binary file (from disk) into memory and then execute it
