> File Install has a dedicated thread for every directory. That thread wakes up periodically
and then does the following:
> 1. Iterates over all the bundles by calling context.getBundles
> 2. Finds out all bundles which belong to watchedDir. It starts them.
> 3. Finds if there is any new jar file in the watchedDir. It installs them.
> 4. Finds out if any jar has been deleted from watcheDir. It uninstalls corresponding
> 5. Finds out if any jar has been modified. It updates the corresponding bundles.
> I think there is some scope for optimization here. Especially step #2 seems redundant
if there has been change in the file system. More over, if out of all the bundles in the system,
only a few belong to watchedDir, then the current implementation performs poorly.
