How about for the time being, any library to help with distributing 
tasks to various threads' queue.
Right now, only Application.QueueAsycnCall has a queue to which you can 
send tasks (  procedure (integer) of object ).
Normal Tthread has  no queues.
I am implementing my own queues for worker thread and encounter some 
problems when the program quits and some objects not being freed at the 
right order.
The application then just hangs (I suppose because some objects are 
still not freed so UI thread keeps on waiting). One of the 4 CPU cores 
is thus at full capacity for ever.

I hope someone has done some work in this area which I can learn from.
