can't reproduce. i expanded your demo to call progress/data/complete callbacks.
attached src and log. downloads both urls - in parallel (well for the first
bit). the first 33.9kb data is fetched completely as is the 64.8k data. i
haven't actually checked the data itself - but everything else is showing "all
ok". no proxy set up here for this test btw. i ran a second test with a proxy
(well proxy fwd'd via an ssh tunnel to the other side of the world) and it
works too with slightly different fetch ordering.

attached logs+src. my svn updated and completely rebuilt just before this test
was run.
