Yes, but it's an issue with the BufferedWriter implementation, since it
changes the length of its underlying bytearray object. If it was
rewritten to use a fixed-size bytearray, the problem would probably
disappear.

(in the middle term BufferedReader and BufferedWriter should perhaps be
both rewritten in C)
