  Modified files:
    sys/kern             kern_sig.c 
  Log:
  Fix long standing bug that prevents the PT_CONTINUE, PT_KILL and
  PT_DETACH ptrace(2) requests from functioning as advertised in the
  manual page.  As described in kern/35175, the PT_DETACH request will,
  under certain circumstances, pass an unwanted signal on to the traced
  process upan detaching from it.  The PT_CONTINUE request will
  sometimes fail if you make it pass a signal that has "properties" that
  differ from the properties of the signal that origionally caused the
  traced process to be stopped.  Since PT_KILL is nothing than
  PT_CONTINUE with SIGKILL, it is broken too.  In the PT_KILL case, this
  leads to an unkillable process.
