When I was trying `procstat -k', I was getting the message:

      PID    TID COMM             TDNAME          
    procstat: sysctl: kern.proc.kstack unavailable
    procstat: options DDB or options STACK required in kernel

That was with a single `-k'. I can't do anything now, because -- after 
an attempt to start `systat 1 -vm' -- the system hosed and would not 
start new processes. The existing ones, such as the cvs-over ssh are 
stuck in:

    load: 0.00  cmd: ssh 59098 [proctree] 0.41u 0.17s 0% 0k
