                          Linux has a stable syscall ABI, but NT doesn't, Windows just ensure Win32 ABI is stable, which will not trap into kernel space immediately. Lower level functions of Windows like nt.dll might change between Windows Update or Windows Editions.

I want to know for other kernels, like FreeBSD kernel or Mach, do they provide stable syscalls or just provide stable ABI of POSIX interface?
