ps under FreeBSD

[Jakub Filonik <sirat () fremen g0ds org>]

Hi,
I was playing with ps on FreeBSD with kern.ps_showallprocs=0 and I was
surprised when I have seen that I may see info about running process, if I
know it's ID

sirat@fremen:ttyp3:~> ps -u5710
USER    PID %CPU %MEM   VSZ  RSS  TT  STAT STARTED      TIME COMMAND
seeba  5710  0,0  0,0  1388    0  p6  IWsJ -         0:00,00 -tcsh (tcsh)

I may see also root's processes:
sirat@fremen:ttyp3:~> ps -u205
USER   PID %CPU %MEM   VSZ  RSS  TT  STAT STARTED      TIME COMMAND
root   205  0,0  0,1  2064  264  ??  IsJ   9:23     0:00,05 /usr/sbin/sshd


and ps axu gives:
sirat@fremen:ttyp3:~> ps axu
USER    PID %CPU %MEM   VSZ  RSS  TT  STAT STARTED      TIME COMMAND
sirat 40384  0,0  0,1   428  272  p3  R+J  18:53     0:00,00 ps axu

I think it may be seen as bug. What do You think?

P.S. I have FreeBSD 4.6-PRERELEASE #0 and I checked it also on 4.5-STABLE
P.P.S. It works like that: ps -<argument><pid> and the argument isn't needed
