It would be useful to have a limit, but keeping one which is a result of 
a bug, and only applies under Linux, and maybe only under 32-bit Linux, 
and is an arbitrary size, and which breaks dnsmasq when it's reached is 
not good.

I think that logrotate/syslogd maybe are probably better places to solve 
the problem.
