As we still don't have a data_page_dir support yet, transfers of more than
65535 bytes blocks silently broke. So limit ourself to 32k blocks, for now.
That mistake gave us the false impression that huge transfers were fast.
They usually resulted of 0-byte transfers. Fast indeed :-(
Now, we have real data going through.
