I see many parts in lib/* that adapts to available system features
like mmap and MAP_ANONYMOUS.  I don't see why memfd_create should be
an exception.  Using a volatile file is much better than forking, and
this only requires a one-time implementation of a wrapper library
function that returns -1 if the feature is not available in the
system.  It should be easy to integrate with the current code since it
returns an fd.
