And one further point: what is the userspace interface going to look
like for this system call?

Are we to see a repeat of the unsafe userspace implementation of
pselect() that was present in glibc before the kernel finally added a
pselect() system call?

In other words: is the userspace interface for accept4() going to be
the thinnest of wrappers, or will glibc add an unsafe
paccept()-with-signal-mask in userspace?
