Hi Simon and Maarten,

we discovered when playing with NetworkManager-ci [1], that lastest
release is somehow broken. Test running dnsmasq are quite slow on latest
release.

I have created repeatable started script that reproduces it. Then used
git bisect to find when it was broken. It seems fast sending were
intentional in commit 0a496f059c1e9 [2], but maybe way it affects the
system were underestimated. It is significant for systems that hit such
issue. I think it has to be fixed to slow it down to short time
interval, not endless loop. Reported as Fedora bug [3].
