Details:

When torrents contain 0 byte files they often dont finish.

The workaround below simply doesnt write to 0 byte files.
Its meaningless to write in this case, so the workaround appears safe. on the
other hand, this case probalby should be handled further up in the call chain.
thats why its a "workaround".

This was spiralvoices idea, I tested it on a problem torrent and it worked.

in unix32.ml
    let file_write file in_file_pos s in_string_pos len =
      if len ≠  0 then  begin2
        let len64 = Int64.of_int len in
        let in_file_len = in_file_pos ++ len64 in
          FDCache.write file.fd in_file_pos s in_string_pos len;
          file.current_len ← max file.current_len in_file_len
      end else begin
         lprintf "debug:0 len file"; (*JAVE try to fix 0 file torrent
corruption*)
      end
