Comment 2 for bug 1357226

This may or may not be relevant here, but the mysterious "uncaught target signal 11" error was fixed for maas images (lp:maas-images) build process by increasing the memory to the VMs that were doing the build. We had been doing the cross/qemu-static building in ~512M vms and that was resulting in somewhat transient failures during 'apt-get update'. Upping the memory of the vm to 2G made those go away.
