I can sort-of confirm this, but on 6-STABLE, 4BSD scheduler, and not 
"all CPU" but just an unreasonable chunk. The usage seems to increase 
with load (this is a PHP+pgsql web server): as the load increases, 
bsnmpd uses more and more CPU. Don't know exactly what causes it - could 
be network or disk IO (does it somehow "listen" for IO events??). As 
this is silly and I need the CPU for Real Work, I've disabled it.
