Once we open the commands to userland this way, it's difficult to
throttle it back again.  I just fail to see the point of allowing
everything possible.  There's a way to override it (is that in yet?)

with justification and can you please stop labeling reviews as
"useless"?  For Pete's sake, if you disagree, just disagree and
explain your point.  How is discussion about which commands should be
allowed via SG_IO "useless"?  Gees...
