High Memory consumption fix

I have a problem with Physical and Virtual Memory, the values are really high.
well, the chromium framework always seems to take a lot of resources… .

Then, when I launch FDM v5 alpha, my Virtual Memory is +900.000Ko (Kilo-octets), and after 3 hours of runing my Physical Memory is +800.000Ko too… it's a real problem, normally I close and restart FDM 5 each hour to clean memory, but with a download of 4 hours it's not possible ^^".

I would be really glad to see a fix for this, I think that it's really important to have the new FDM with more or less the same specs as his predecessor.

Thanks !
