[OT] cache library suggestion

[Magnus Damm <magnus damm gmail com>]

Hello All,

Sorry if this is a bit off topic, but could someone recommend me a
cache library that handles storage, lookup, ageing and invalidation of
data? I am thinking about how nautilus handles thumbnails or how a
browser stores/looks up data in a cache.

Things that could be improved by a cache like this:
- PDF/PS rendering/thumbnail generation
- List or extraction of tar/cpio files
- gz/bz2 seek without decompression
- storage of keyframes from a video stream 

Any suggestions?
