Enable swap space on some Chromebooks to give tabs more memory

Perhaps the most frustrating aspect of Chrome OS, even for those who generally dig it, is when you head back to a tab and discover you have to wait for it to refresh. Chrome OS only has so much memory to hold the content and interactivity of a page. But that seems odd, if you know that the Chrome hard drive is made of the same kind of speedy flash memory as its, uh, memory.

So: you can try this out, on certain (Intel-based) Chromebooks, if you're on a certain release of Chrome (beta and dev seem to work).

1. Open "crosh" (press Ctrl+Alt+T)
2. Type "swap enable" and press enter.
3. Restart your system.
4. To test if your system has enabled swap space (a.k.a. "zram"), open another crosh session (Ctrl+Alt+T), type "swap status" and check the result. If you see "/dev/zram0" listed under the "filename" header, you've created a small space on your hard drive to act as a kind of backup memory.

On stable, I can edit crosh, but it did not set up the zram (even though it acted like it would on reboot).
+Morgan Whitfield Right. Crosh is built into every Chrome device, but only Intel-powered devices can enable swap right now, it seems. Different kernel, methinks.
zram does work on the beta channel for ARM.  I swapped over this morning.
