struct SingleRequest has two variables that serve two very similar purposes,

Yet, in tracing through the code, they seem to be used fairly
interchangeably. I am curious what the real distinction between the two of
them is because it's not abundantly clear to me why there should be two
separate variables given that they seem to (almost?) always be set to the
same value.
'size' is the discovered size of the entity that is to be downloaded.
'maxdownload' can be a pre-configured maximum amount of data to download, but
if it isn't set to something it is often set to the value of 'size' to make
things handy.
