While working on other problems with *printf(9), log(9), etc.
I stumbled upon:
options PRINTF_BUFR_SIZE=128 # Prevent printf output being
interspersed.
Question 1: Am I correct in thinking that PRINTF_BUFR_SIZE is

Just tried dys_sysctl. It doesn't work as well.
Below are the results I got:

There is no buffering comparable to that of the stdio p
Thanks for all of your replies. The reason I asked this question is that I
really saw some incomplete print out on FreeBSD 3.3. My intuition is that
the printout is buffered some where, otherwise, I would expect either
there is a complete printout, or no printout at all.
