When adding a directory containing recursive symlinks with KDirWatch::addDir, telling KDirWatch to watch recursively with WatchSubDirs flag, it ends up recursively watching the same directories (it stops somewhere, but I'm not sure, why).

This might be causing gamin to use 100% CPU, not to mention other resource usage; this also might be (one of) the cause(s) of bug #161380 (I actually discovered it by noticing that strigi had been running for 24 hours and still indexing, while two nepomukservices had been saturating the CPU).

You'll find attached a testcase. I'm working on a fix ATM.

After running the testcase, you should see (assuming you have debug messages turned on) something along the lines of:

bar(8682)/kio (KDirWatch) KDirWatchPrivate::useFAM:  Setup FAM (Req 1) for "/tmp/foo/foo/bar/baz/bar/baz/bar"
