Detailed Description

Event generator to poll for completed tasks.

When Houdini has an opportunity, it will call this class to process any events. Ideally, we would use the FS_EventGenerator::getFileDescriptor() method to return a file descriptor which allows a select() call to be used rather than a polling process. However, in this case, we need to poll the background processes.
