Showstopper ? Userland prozesses showing up as kernelprocesses with AMD opterons ?

bind         729  0.0  0.8 17356 16808  ??  Ss    4:12PM   0:18.27 [rbldnsd]            100
clamav      2672  0.0  1.8 37684 36644  ??  I     4:16PM   0:00.00 [mimedefang-mult     100
clamav      2625  0.0  1.8 37684 36644  ??  I     4:16PM   0:00.00 [mimedefang-mult     100

Correct. Those are not kernel processes, they only have 0x100 as flag which
means;


               P_SUGID             0x00100      Had set id privileges since
                                                last exec

World and kernel are in sync. Something

# sysctl -a kern.ps_arg_cache_limit
kern.ps_arg_cache_limit: 256

It's still strange. Could this mean that modifing id privileges looses all
cmdline args ? That's really bad if this is true.
