[Opensim-dev] Please do not revert fixes without carefulcomtemplation [text][bayes]

[Dirk Krause]

Holy Frag.  I see now, thanks for he explanation, I didn't know that.

This is ... err ... a major issue, to put it mildly. To put it straight this design is a royal pain,
and I wonder whether it isn't imperative to address this SL imported issue *before* anyone tries
to optimize the hell out of whatever database.

OpenSim, and the client, are full of "eternal caches". They don't 
update, there is no TTL, and no update check. Assets are immutable 
by design and the applications are written to assume that assets 
will never change. Therefore, the caches never expire.
