Every time, on a dual core Pentium D running XP64. The program is compiled 
as 32 bit with MSVC 7.1. It looks like a livelock rather than a deadlock, 
since the program keeps spinning its wheels at 100% but never completes. The 
writer thread is probably either blocked or starved. This happens on another 
(quad core) machine too for which I don't know the specs at the moment.
