Subject: [PATCH] Fix fowllowing problems:

1. If fork()ing, the program is executed twice.
2. If the ktruss(1) output is bufferd, the final output is not flushed
   (because it is executing).

    % ktrace -f - rm >/dev/null
    usage: rm [-dfiPRrW] file ...
    usage: rm [-dfiPRrW] file ...
    % ktruss date | cat
