Updating network.http.max-persistent-connections-per-server causes firefox to stop loading pages

Note that just multiplying the two values together isn't necessarily what the user intended.

Often downloads may be from different sites, so as long as the total number of connections (network.http.max-connections is sufficient we're ok)

For example I'd want something like

• max connections per server : 6 (try to be sociable)
• max connections for down them all to use per server: 4 (leave some for regular browsing)
• max simultaneous downloads: 4 (from different sites)

If I was to download 2 files from the same site I'd expect downthemall to use ~50% of it's quota per download

Hope I've explained what I think the intent is, and the problem

Finally note the problem is likely most evident when the max-persistent-connections-per-server is greater than max-connections-per-server

We rely on these preferences as well, so not overwriting them is not an option.

I checked in some code to abuse those settings less. source:/trunk/chrome/content/dta/manager.js@160#L133

About fine-tuned total/per-server settings in dTa: This suggestion is already tracked elsewhere. ;)
