Actually, it's the case _on VMS only_ that lynx does _not_ always copy -
it tries a rename first() and falls back to copy if the rename fails.
I see no reason why the same logic _couldn't_ be implemented for UNIX
etc., but I do prefer the current behavior (even though I *do* frequently
run out of tmp space)!.

Not sure what you mean - how you define "currently in-use".

Actually only the one temp file downloaded most recently is still usable
on the "Download Options" page, but others may hang around for some
time longer (until anchor->FileCache gets removed).  That makes sence
IMO because someone may have started running a DOWNLOADER command
on one of the previous download files that operates in the background.
