I didn't really pay any attention, until by chance, I was
looking into the taskbar and saw I had a whole swarm
of "chrome.exe" running. Here is a snapshot, when I
had four tabs open in chrome. One tab had flash objects
(no video was running though).
It amounts to ~423K of RAM, combined, for Chrome.
We like to bash FF for consuming RAM, but it takes
dozens of tabs and flash to get it anywhere close to
what Chrome eats up, behind our back.
Here is a thread on Chrome forums, where people
are discussing this phenomenon.
