the makefile method so that it is compatible with the standard socket
interface and usable with httplib.

response into a file-like object. This implementation reads using recv
and copies the output into a StringIO buffer to simulate a file object
for consumption by httplib
Nb. Ignoring optional file open mode (StringIO is generic and will
open for read and write unless a string is passed to the constructor)
and buffer size - httplib set a zero buffer size which results in recv
reading nothing
