how to confuse truss: truss -f fsck -p /

After typing "truss -f fsck -p /", I see nothing. I press ^Z
and type kill -9 % (killing truss).

I now have these fine processes hanging dead in memory, they are immune
to kill -9 and don't respond to kill -CONT either, ps axl:

  UID   PID  PPID CPU PRI NI   VSZ  RSS MWCHAN STAT  TT       TIME COMMAND
    0 56974     1   0   8  0  1256  744 ppwait D     p1    0:00.00 fsck -p /
    0 56975 56974   0   8  0  1256  744 stopev DV    p1    0:00.00 fsck -p /

Is this how things are supposed to be, even though killing a tracer is
way stupid? I think it's not nice to have unkillable processes.

Is there a way to get rid of these without reboot?

Is there anything I can do to help debug this?

The software is quite current, half a day maybe.
