i have simple test that works as:
1) boot 3.18.x kernel and initrd with static compiled golang binary
2) binary bringup dhcp network
3) fetch from http gzipped raw qemu image
3) in parallel decompress gzipped image and write it to disk

this use-case determine previous error in qemu (that brings this discussion)

I'm test you and Hitoshi patch with qemu 2.4-rc0, i'm compile two
independent debian packages with you patch and with Hitoshi.
Install qemu with you patch to one node and with Hitoshi on another.
Runs sheep with local cluster driver.
I don't know how to determine qemu segfault in my case, does it
possible to build qemu with debugging via configure flags ang get more
detailed descriptions?
