An introduction to Clear Containers

Yes, that includes the startup time of QEMU (and I should not take timings on a laptop, because now I'm getting 50 ms). Time is mostly spent in glibc, except for a single function that costs 25% and that can be easily brought down to 10%... i.e. 40 ms. :)

I got it with "time", modifying the firmware to exit QEMU 10 or so instructions before the jump to vmlinuz.

And it can do migration too, of course. :) What is the expected lifetime of these containers?
