Users of a fax server noticed this problem, that at some point in time
retrieving the faxfile (say ~100kB) from web-frontend took way too long, while
cpu rockets to ~100%.
I found that their dl list was pretty long. Trying to remove elements from such
list in dl.manager was a pita, takes ages; so I did the rough way, and deleted
.mozilla/*/*/downloads.rdf
which solved the issue.
Can't tell if such .rdf went broken somehow, though, only that mozy did not
complain, happened on a few machines, with same details as above - so I guess
the issue here is long list+inefficient .rdf parser.

I think that, regardless of any bugfix/algo improvement, there should be some
aging option the user can set, to prevent unbounded growth.


Reproducible: Always
