<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Hm, not sure. The DirWatch only wakes up when kdevelop writes to the session files, which is "not that often", and given that the system is running at that point anyway, it won't cause unnecessary wakeups.
When doing loadSessions() after krunner is pulled up, this touches disk and adds latency to krunner being available, so I'm not sure that's what we really want. (I can imagine delaying the first loading of sessions to the first teardown() appearance, though, to not unnecessarily touch disk on startup.)
I've tried putting the new KDirWatch after prepare() and deleted it after teardown() signals, but got crashes in KDirWatch::addDir() after it's deleted once. I assume threading havoc here.</pre>
