Modified files:
sys/kern kern_ktrace.c
Log:
Remove process information leak from inside a jail, when
security.bsd.see_other_uids is set to 0, etc.
One can check if invisible process is active, by doing:
# ktrace -p <pid>
If ktrace returns 'Operation not permitted' the process is alive and
if returns 'No such process' there is no such process.
