Safety was/is certainly a concern and is good that is brought up here. 
I did make sure I was alone in the house in a well ventilated kitchen with the hood running at the time and I did run the oven for an additional hour at 250 C to get rid of any possible residue.
I would certainly not recommend turning one's kitchen to reflow repair facility, but I must contest the logic of "avoid what you do not know". Living in a world that less than 0.1% of the chemicals that we are coming in contact with every day have pass any serious, if at all, safety testing, this approach is more philosophical than useful or protective. 
Having said that, in cases like the XO boards I think that we could and *should* know, at least the chemicals involved
