* TaskBuildIndex starts seperate indexer processes and communicates via shared memory * indexer processes get restarted if they fail * indexer processes are killed when the app closes or crashes * added utility class SharedMemory to allocate and access shared memory, providing basic data structures * added SharedMemoryGarbageCollector for keeping track of running instances and cleaning up shared memory in case of a crash * show errors for source files that crashed during indexing * added basic exception handling to task scheduling * added option to turn off processes and use threads in preferences, but still use shared memory fortune cookie message = Good news from someone dear is coming soon.
