Operating System

Hello, /prog/. If you had the perfect operating system for writing games in, what features would it have, and what features would it lack? What qualities does the perfect operating system have, and what qualities make you want to stab the people who programmed the OS?

Also, the file directory tree sucks ass.  Many times a large set of data files are NOT in any hierarchical order, or the one chosen hierarchy works out as shit when you want to sort information in a different way, or have multiple sets of ways of looking at them.

Having interlinked indexes of some sort, tags that refer to data in some sort of knowledge base, etc, would be far, far better.
