This is an opaque sysctl. You can use the (-o) flag to see the format 
and the first sixteen bytes or use (-x) to see the full output. There are 
plenty of these in the sysctl tree, they are just not normally conveyed 
directly to the user without the proper flags given as the output is not 
very useful to the human eye and contains to much output in any other 
format to be useful.

What this one specifically relates to IDK, maybe someone else can tune in 
for further information.

See ( sysctl -A ) for further interesting details.
