Urlopen.urlretrieve(url, to) can it be canceled/stopped/killed

[Justin]

does anybody know if there is a way to stop urlretrieve mid transfer or
are you simply bound to finishing the file you are on?  If anybody
knows the answer to this let me know.  i have read all the docs and
there is a callback or reporthook function, but I am not sure if that
can be used to halt the progress and close the socket.
