Use urllib.urlopen(), but call .read() with a smallish argument, e.g.:
>>> foo = urllib.urlopen('http://google.com')
>>> foo.read(512)
'<html><head> ...
foo.read(512) will return as soon as 512 bytes have been received. You
can keep caling it until it returns an empty string, indicating that
there's no more data to be read.
