Then perhaps it's not the same bug.
Please take a look at CPU utilization during the download. If Python takes close
to 100% CPU, it might be due to the lack of buffering or any other suboptimal
situation in the implementation. If Python takes close to 0%, then it's just
waiting on data to arrive from the network...
