Title: Re: Implementing Batch Requests in GConf

Hi everyone,

Looking a bit closer at this armed with the knowledge of how GConf preloading works I began to become suspicous of how Metacity racked up hundreds of GConf roundtrips. It only has a handfull of GConf dirs it queries so it should only be making that many calls to the daemon..

It turns out that Metacity queries many keys that simply aren't set on my system, including the names of 36 workspaces and a seamingly endless list of keybindings. These don't appear in cache even with preloading so we end up making a roundtrip to the daemon for each one.

The way I'm thinking of solving this is by considering keys that don't appear in cache but are covered by a previous add_dir as unset without bothering the daemon. I don't see what that would break but I'm completely unfamilar with this area so I could use some guidance.

Also, I've mentioned Metacity in particular but I'm sure.this applies to lots of other apps.
