no need to reset the stream here (a new stream's cursor always points to
the first byte)

reset the stream *here*.

CamelStreams are just like normal POSIX file i/o... if you do:

fd = open (file, O_RDWR);
write (fd, data, len);

the cursor into the file is 'len' bytes into the file now and so if you
want to parse the resultant file from the beginning, you have to seek to
the beginning of the file, or any reads() will start at offset 'len'
