Yes, it seems I'm getting EINVAL.  But the EINVAL is coming from the
mmap() call, *not* the initial tests in rszshm_mk() which explicitly
set EINVAL.

But what's *really* weird, is I get it when I run ccanlint directly,
but not when it then re-runs the tests under gdb.  And as far as I can
tell mmap() is getting exactly the same arguments :/.
