User agents may store expired pages for offline use. Internet Explorer
and Firefox have 'Work offline' modes automatically enabled on
complete disconnection from the network. Currently, only cached pages
and sites explicitly selected by the user are available offline, but
given enough disk space, user agents might keep all files of MIME type
"text" (e.g. text/html and text/plain) - or even all files.
The variation on constraints between systems is such that even looking
only at my desk there's a system with over 1.7GiB of free read-write
memory (0.5MiB magnetic, 1.3GiB volatile RAM) and another one with
under 300MiB (volatile RAM). I don't want authors to be able to use up
my memory by storing most or all content for offline use, nor to
unnecessarily loose access to content when storage space is plentiful.
