From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Yes, and that's a good thing if you don't want it to start killing processes. You have that extra time/space to deal with the out-of-memory condition yourself.
Or you can ignore that condition and continue using the system in a degraded state, with swap as "disk RAM".
Like I said, the system will be almost completely unresponsive due to disk access being several orders of magnitude lower than RAM and allocation thrashing... you won't be able to do much, the mouse, keyboard and display will react extremely slowly. There may be situations where you'd prefer this to an OOM kill, for example if you're running a test or experiment where you'd rather have it finish even if it takes a very long time rather than lose the data. But if you're a regular desktop user or server admin you'll probably just reboot.
