I think that the overhead is worth it. We rarely move these things,
so optimizing for that case is less useful than knowing what's a
system call and what's a library call.
System calls live in section 2 and library calls live in section 3.
Even if we call them all functions, and have to move them around from
time to time, that's a good thing and something I would actively fight
against changing.
