We've been over this many times already, and there's no point in
The bug is the "the foo() call will fail if" text, not the inclusion
Here's an additional consideration:
Currently, pipe(2) is implemented as a two-return-value syscall;
support for two-return-value syscalls currently imposes additional
overhead on *every* syscall, which slows down every syscall by a few
One possible way to fix this would involve changing pipe(2) so it's a
"normal" syscall which *may* return EFAULT; other two-return-value
syscalls would also need to be changed.
