the trace.

[ktruss] Use fork(2), not vfork(2).
...
The child process of do_ktrace() does return and the stack is
changed by another function call (execvp()).
By using vfork() (my previous change), the execution of the parent
process resumes on the modified stack. Oops.
We could use vfork() carefully, but for now use fork().
Problem reported and investigated by Ethan Solomita <ethan@geocast.com>.
Thanks.

Make ktrace(1) not affect interactions between processes.
...
Following examples show the cases.
% ktrace -f - false >/dev/null && echo wrong
wrong
% ktrace -f - -i /usr/sbin/update >/dev/null
(does not return to command line)
That is, back out last change and restore the roles of parent/child for
ktrace(1). The ktruss(1) stuff still remains.
Yes, ktruss(1) has the problems. Better implementation is expected.

2. If the ktruss(1) output is bufferd, the final output is not flushed
(because it is executing).
