 From a brief poke myself (and I'm no overseer) I'd hazard a guess it may 
be more to do with the 17 simultaneous cvs checkouts as well as 2 rsyncs 
and a couple of ftps. netstat also seems to be reporting a TCP SYN attack 
from tproxy1.NTCU.net (62 sockets in SYN_RECV state).

I don't know about the "supervise" thingy but I know xinetd has a 
"max_load" parameter that could be used to e.g. deny anonymous (not logged 
in) cvs over a certain load (since having 10 cvs operations complete two 
times is better than 20 cvs operations taking nearly forever).
