Relax.  There's nothing to worry about.  In fact, I'd say go for it,  
but not on your production machine.  If you are successful, please  
post back.  I've tried several times as root and was resoundingly  
rebuffed each time with "Operation not permitted".  I've also tried  
'echo > /proc/kcore'.  Didn't get an error, but nothing changed, either.

Never?  That's probably a bit overreaching.  /proc is a really  
convenient way to modify your system's settings.  In fact, a grep  
through the /etc files shows that many configuration scripts do just  
that:

   grep -r '> *\/proc' /etc

/proc is probably one of the least understood, yet probably one of  
the most powerful features of Linux.  I'd say setup a spare system  
and start poking around in /proc.  You'll learn a lot.  'man proc' is  
also a fair read.  It's not great, but a start.
