   @clebertsuconic About the memory barriers? Are the standard implementation used on the
c++11 memory model and I have asked a colleague of mine that work on the Linux kernel, specifically
on libAIO ie Paolo Bonzini on https://github.com/redhat-cip/fio/blob/master/engines/libaio.c
   
   Memory barriers instead are on: https://github.com/redhat-cip/fio/blob/f42557f8ba1fc6bbf6b5fce4ae3a53cfc8bbb35b/arch/arch-x86_64.h
   
   Probably for 32 bit we need to include a different implementation or just use C11 that
already define them for each arch, wdyt?
