Importing from wordpress exported file renders "Remote file is incorrect size" because file cache

[stelund]

Hi,

I haven't confirmed this on other platforms, but my OS X machine seem to have an issue when downloading media content from a third party during an import of an wordpress.xml. And by quickly searching the net it seems other people have the same issue.

I've re-run the same import several times and it seem because the file was not flushed it may not have been updated with the file correct size. So even thought all bytes was written, the filesize($uploadfile?) is not the same. When thinking about the issue I found the check ridiculously and removed it. Importing then works and all media images are downloaded properly. Previously maybe 50% received the error.

I've attached my proposed diff.
