It has some interesting scheduling problems on SMP when using a
distributed setup (local tests as well as remote tests via NSCA
persistent daemon).  If you hit the problems (lots of processes
backing up), strace the parent process and the problems go
away... makes trying to find the 'real' problem practically
impossible (our startup script just runs a strace 2> /dev/null
now, and no problems).

Anyway - yes, Nagios or SNIPS are more likely to be used than
spong/BB in larger installations.
