Simple servers, especially written in high-level scripted languages with
gc (Python or Scheme) don't crash so easily.

If power goes down and no UPS is available, the server goes offline.
It will boot up fast enough (LinuxBIOS can boot up in ~10 s, and use
fsckless file systems to fill the RAMdisks with).

Nothing can happen to the database itself, as in my case the database is
entirely static.
