No. They recently changed it so if you open a link from one tab in a new tab, the new tab is a child of the previous tab. I think that's how it works - don't really know, just seems to be the case. Either way it saves on ram without severely compromising stability. Just press shift+tab in Chrome to open its task manager thing and you can see which tabs are running in the same process.
Quote: "Only kernel-level software (ie. drivers) can cause a BSOD, so your story doesn't add up."
Yeah but if a driver has a bug or slight incompatibility with the system, crashing a normal user program (Chrome, for instance) could cause the driver to crash and cause a BSOD. It's perfectly possible and in fact a normal occurrence. Have you never had a game cause a BSOD before?
Quote: "(I have no idea how memory is handled by the OS in a case where you run out of it completely)"
If you run out completely or the page file can't keep up (if it's on an old, slow HDD for instance), programs crash, task manager won't open properly (like some parts of the gui load and some don't - very weird), graphical elements corrupt, and Windows crashes. I've done it many a time by forgetting I have 70-80 Chrome tabs open and then launching GTA V (with only 8GB ram)
Also it makes your hard drive go flat out trying to keep up
