It is possible that my Windows has been infected while dnsmasq was crashing. I don't know for sure if it was infected, it might have something to do with a crack for DVDFab, or it might be a perverse effect of installing VMware. What I know is that I lost keyboard and mouse control over Windows. I have restored Windows several times from backup and after an hour or so I lost every time keyboard and mouse control over Windows. I have then restored from an older backup and it no longer happens.
Anyway, virus infection is not an excuse for dnsmasq dying under stress.
