=46YI, this change will give you an additional memory saving. Normally
ZServer stores the whole response in memory for the duration of it
being downloaded by the client. For a slow client this may be some
time.

However, the Image and File objects ensure that this is buffered on
disk, by using RESPONSE.write and setting a Content-Length header.
(the disk buffering only happens if the length is large)
