Is blackhole linked to /dev/null?  I'd like to see the actual
output from ls -l.  

Of course, Hawkings has postulated mini-blackholes and one might
be living on the top of your hard disk, though it ought to play havoc
with the head as it passes over.  Also, be forewarned that he
thinks they can evaporate over time because of angular momentum,
and would take out a fair sized city when they do.  I doubt if
it is covered under warranty.
