On what kind of filesystem is your project hosted? KDevelop sets up directory watchers for all directories in your project, and I wouldn't be very surprised if for FUSE-based filesystems that means running a polling loop. It does seem incongruous though that this would eat 100% CPU; I don't think KDevelop needs to know about changes in the project source tree with millisecond precision...
