There aren't a *lot* of such system calls, but even in that thread the
"oh, only two applications need this, let them use syscall(3)" seems to
remain.

And only 2 applications will continue to use it because no one wants to
write syscall() wrappers for their individual applications, so it's a
vicious cycle :(

I really like the 'libinux' idea, did anyone every hack up a first-pass
at this?  And I'm guessing we have more syscalls now that would need to
be added (like getrandom(), but that shouldn't be too difficult.

I haven't hacked anything up yet, but I think it would be easy to simply
take the klibc machinery, remove the stuff that isn't needed, and adjust
the handling of errno(3).  I think it is time I admit that it needs to
be put on my TODO list.
