I was thinking along the lines of:

def peek(self, size=None, block=True) I think this is fine too. :)

If 'block' is True then return 'size' bytes, unless the end of the file/stream is reached; if 'block' is False then return up to 'size' bytes, without blocking. The blocking form might impose a limit to how much can be peeked (the maximum size of the buffer), or it might enlarge the buffer as necessary. I guess the limit wouldn't be a problem to someone that chose to block further reads.
