Regarding this one,

it's because HP-UX's exec-family functions are not POSIX conforming.
As described in http://www.opengroup.org/susv3xsh/execl.html, calling
exec* with one or more of the three standard file descriptors closed,
"system implementations may open an unspecified file for each of
these file descriptors in the new process image.", but only if the
exec'd program is run set-ID.

HP-UX, however, does this even when running non-set-ID programs,
thus making what should be a write failure appear to be a successful write,
even though it's to /dev/null.
