 Log Message:
 Make sure we can deliver two file descriptors for pipe2() before we set
 up anything special (like close on exec).
 Fixes PR kern/46457.

Thanks for fixing this. There is at least one other critical, 100 %
reproducable, bug that allows non-root users to crash the system; PR
kern/38889 (see also tests/lib/libc/sys/t_mmap; mmap_block).

- Jukka.

I'm investigating...
But: I don't see how that could work for non-root users.
