Can someone humour me and try this total hack job 'locking around dnsmasq startup' patch that I botched together last night.

I've an AP that doesn't need to run dnsmasq, so rc.local has 
"
/etc/init.d/dnsmasq disable
/etc/init.d/dnsmasq stop
#sleep 110
#/etc/init.d/dnsmaq stop
"

Without the patch it's a lottery as to whether dnsmasq is left running or not which indicates race type issues (hence the now commented sleep & another stop).  I'm wondering if race+jail+dnsmasq is an even worse combination :-)
