Generally, saving something like an image takes much longer than displaying it
in the browser, due to a delay after pressing the "Save" button which freezes
the browser for a few seconds.
The same problem can be seen by saving a file with "content-disposition" header,
or by clicking on a link that requires a helper to be called (like an mp3
player). There is always a delay which gives an overall impression of slowness.
This is regardless of whether the download manager, the progress window, or no
window is shown during download.

I forgot to mention, that Netscape 4 (or IE) doesn't have this issue, so if it
is some temp-file locking issue there must be a faster way of doing it.
