Or run your services/calculations in a VM on Xen that you can snapshot, upgrade the host, and then bring the VMs back up. There are some things you just can't get around (like reboots for core components).
That is worth considering, though managing the memory allocation between VMs might cause more of a hassle than the gain, especially on the machine for calculations which need lots of memory (currently 16GB).
