posix_madvise() doesn't seem to... "otherwise, an error number shall  
be returned to indicate the error"

It documents EINVAL for invalid advice, and so does madvise. Are we  
using ENOTSUP knowingly?

Maybe return -1 and set errno to the posix_madvise() return code? (but  
is it errno = -retval or errno = retval then?)
