I write web server in FPC. I invented lock-free FIFO Queue because I 
need fast message queue between threads (socket  and user interface).  I 
think it is  simple, fast and don't need memory management and garbage 
collections.
I think I have  idea to implement priority queue too. Simple list can be 
implement by Valois (or others) algorithm. But i don't have real-word 
constraint.  FPC has implemented all needed atomic instruction on most 
platforms.  Thus I'm ready to work on this subject.
