Note that this depends on the in-tree system call numbers list, which I
still need to finish according to Joseph's specifications.

(We have something that should work for us as long as we can get large
machines from the lab, but I agree that it's not very useful if glibc
bot-cycle time is roughly one business day.)

Thanks,
