rsync fixups for secondary1

I'd like to do the following to prevent our rsync hosts such as
secondary1 from being overloaded.




diff --git a/configs/system/rsync.xinetd b/configs/system/rsync.xinetd
index 8976dd7..f5b5dbc 100644

This limits the number of simultaneous rsync clients to 10, at most 2
per IP (I had to kill a client with 10 open connections), establishes
a max load above which it stops serving clients, and establishes a 10
minute I/O timeout (no I/O after 10 minutes, close the connection).

These numbers are completely arbitrary, but should decrease the load
seen on secondary1, which tonight was at

04:57:21 up 15 days, 11:42,  1 user,  load average: 95.35, 136.54, 99.04

Acks please.

Thanks,
Matt
