While we're on the subject, can somebody explain to me why we
use ifuncs at all? I couldn't work out why it would be better than
just using a straightforward function pointer -- when I tried single
stepping through things the ifunc approach still seemed to indirect
through some table or other so it wasn't actually resolving to
a direct function call anyway.
