downloadFile has a memory leak.

I have a huge amount of files (hundreds of thousands) that need to download, but the file size is small, from a few to hundreds KB, so I use a loop to do it. And I watched the Perf Monitor, the memory usage are keeping increasing.
I searched the issues about the memory leak and found someone fixed the upload memory leak issue, so is there someone who can help to check this situation existing in downloadFile? thank you in advance.
