Detailed Description
       A runlist is used to restrict concurrent exection to a limited set of concurrent sessions, much like a semaphore.

       However, the runlist differs in that it notifies objects when they become ready to run, rather than requiring them to wait and 'block' for
       the semaphore count to become low enough to continue.

Member Function Documentation
   bool ost::Runlist::add (Runable *run)
       Add a runable object to this runlist. If the number of entries running is below the limit, then add returns true otherwise the entry is
       added to the list.

	   true if immediately ready to run

       Parameters:
	   run pointer to runable object.

   void ost::Runlist::check (void) [protected]
   void ost::Runlist::del (Runable *run)
       Remove a runable object from the wait list or notify when it is done running so that the used count can be decremented. Parameters:
	   run pointer to runable object.

   void ost::Runlist::set (unsignedlimit)
       Set the limit. Parameters:
	   limit to use.
