I was asking for a way to don't have to publish the complete file at
once. For example:

fd = publish_*(...)
while True:
    buffer = fd.read(512)
    if len(buffer) == 0: break
    sys.stdout.write(buffer)

Note that this is just an example, I know that i can write to
sys.stdout directly. But sometimes i need a file like object to pass it
to an other function which expects a file-like object. In this case i
could create a StringIO but this would be waste of memory and
performance. Thanks
