Optimization in KDE Base
Performance improvements for deleting local files.
Deleting 1000 local files (without progress info dialog):
before: 4177 ms with independent jobs, 3860 ms with one job
after: 1010 ms with independent jobs, 150 ms with one job.
End users selecting 1000 files in konqueror fall into the "with one job" category, so this is a 25-times speedup.
