That's not what is happening though. I try to open a page in konqueror
(I also tried other programs, it's not specific to konqueror): I see
two request (A and AAAA) going out at the same time; konqueror says
it's unable to resolve the address - so far so good. I try to reload
the page and I still see both requests going out at the same time
(failure again). With single-request I see the first query, its answer
and only then the second query and its reply - as expected.
Furthermore I fear the workaround won't work for one-shot programs,
like apt helpers, right?
