To be fair, part of the problem is that we don't have good
documentation about best practices in what people should do if adding
new system calls.  (i.e., creating a man page and pulling in Michael
Kerrisk, adding tests, wiring up both x86_64 and i386, sending mail to
linux-arch, the scripts/checksyscalls.sh script, etc.)

I'll confess to being ignorant about the checksyscalls.sh script, and
while I had known about the existence of the linux-arch list, I had
forgotten about it, so if I had tried to add a new system call, it's
likely I would have missed at one or more of these steps.
