Martin is right. However, I don't how Python handle the case where 
bytes_available is zero (in C, an error value is returned and errno is 
set to EWOULDBLOCK).

When I revised the patch I had a weak understanding of nonblocking I/O. 
I thought the "exponential" reads were for nonblocking I/O, but I see 
now that is non-sense.

I am not sure, but I think Martin is also right about the second loop. 
The max() call should be changed back to "max(self.buffer_size, n))", 
like in the 2nd patch.
