I apologize for releasing the new singleton code before I tested it... I got so excited that the changes were done that I wanted to put it up before I had to leave, and now that I have tested it, I found some blatant compilation errors that needed to be corrected. However, I can now say that the code has been tested, the bugs have been fixed, and the longevity lifetimes work perfectly. They even are destroyed in reverse order of creation if they have the save longevity, as the owning longevity registry singleton takes that into account (I'm not just getting lucky with how my version of priority_queue happens to be implemented). at_exit is never used, and there are no source files to be compiled. The new code is uploading now, and should be corrected by the time this message is received. Did I beat Loki yet? ;) Thanks in advance for all replies and further suggestions. -Jason
