public final class OSROrganizerThread
extends RVMThread
extends RVMThread

Organizer thread collects OSR requests and inserted in controller queue The producers are application threads, and the consumer thread is the organizer. The buffer is RVMThread.threads array. The producer set it is own flag "requesting_osr" and notify the consumer. The consumer scans the threads array and collect requests.
