It might be useful to use `zram` in Tails.

* Linux 3.8 ships a faster lzo compression module, that's used by zram
* Ubuntu's Live systems have enabled compcache (zram's ancestor) in an
initramfs script shipped by casper on systems with no more than
512MB of RAM between Intrepid and Precise. Disabled in Quantal since
compcache does not exist anymore.
* Daniel Baumann's [initial testing
was quite sad: "i've tested it quite a bit with the idea of
enabling it automatically on debian-live systems if the machine as
not a certain amount of physical ram available. had only bad
experiences with it, so far (worse than without it)". He experienced
"complete lockups/panics, and general 'so slow nearly death'
experience of the system" on 1GB systems with no disk swap enabled.
He was giving sometimes half, sometimes 3/4 of the system RAM to
