Modified Files:
        src/lib/libc/sys: close.2

Log Message:
close(2): Document the finality of closing.

Even if close(2) returns -1 on error, the descriptor is closed (or
was already closed).

POSIX doesn't specify this, but that's a bug in POSIX (probably to
accommodate some buggy ancient proprietary Unix).  Every free
software OS kernel I checked works the same way and it is important
to be able to reliably close descriptors with finality.
