Yeah, you can do it that way too right now, but I don't want to assume
that we're always going to use a system call or that it's always going to
be as simple as calling syscall.  I can imagine possible future changes
(particularly with Linux, where adding syscalls is a pain in the ass)
where this might not necessarily be the case.

I think a simple shared library is a better long-term solution for
providing the interface than just a header file, since it can then cope
with such changes and should have an exceedingly stable API.
