The gratuitous inconsistencies between platforms is something that is
currently driving me up the wall. I'm starting to think the NetBSD
people have the right idea: when you add a system call on NetBSD, you
only have to add it in one place and it becomes available on all the
platforms they support. Of course, you can provide a custom
implementation for any one platform, but the idea is to keep as much of
the code generic as possible...
