Humm, I now fully understand the bug, which is a (small) design flaw in the
new background download system. To summarize, html files are not anymore "put
on a list for later download", but rather "checked immediately" (on-the-fly)
to solve difficult issues such as redirects, errors and mime type mismatch.
But it means that the html link heap is going to be stored in memory until all
html files are checked out, and not only it fills the memory, but it also
fills the "backing" structure, which explodes.

The current alpha release fixes the problem, by storing downloaded html files
as temporary files, and removing the entries from the memory (and only keeping
a link to the filesystem structure), but the 3.40 series do have this

Another good reason for me to speed up the 3.41 release process :p

In the meantime, you can give 3.41-alpha a try.
