From JBIDE-10974:

> 9. Every change in build component triggers full rebuild for all components

9. This could be fixed by instead of watching the /build folder in SVN for changes, we simply fetch it using `svn co` or `svn up` as a prelim step in the job.

Perhaps taking this a step further, we could fetch the whole SVN tree and store it outside the workspaces so that jobs would simply re-use local shared space instead of clean-fetching everything every time they run on a new slave.

This would of course make jobs "more tied to infrastructure" and "harder to build the same way offline" but that's the price you pay for optimizing for speed.
