   I had to comment out support for that sysctl due to design problems with
it resulting in systemn crashes. Sysctl just isn't up to passing potentially
10's of megabytes back to user processes. Further, there is also a significant
security concern with providing so much information about all of the open
files in the system.
   The information provided by pstat -T can be had via sysctl(8) and pstat -s.
pstat -T should probably be nuked entirely or changed to use other mechanisms
to get the information.
