I was suspicious of those as well. It might be a good idea to at least write
such failures to stderr, otherwise it's just about impossible to debug. Not
that stderr will always point anywhere useful...

I can imagine that a system under heavy memory pressure might fail writing, if
there's a lot of writes in a row or such.
