<alternative exemplar> When I implemented the Leader-Follower thread pattern described by Schmidt, et al in Pattern-Oriented Software Architecture, I couldn't figure out a way around comparing the thread id to the current leader in the promote_new_leader function. Probably lack of imagination and/or experience on my part, but having the thread id sure made it easier.
If all you need is comparisons, the boost::thread class provides

today. That's why I wanted specific requirements for a thread id. Currently the things a thread id can provide that thread does not, AFAIK, are the following:
* Can be copied. * Can be turned into a unique string for printing/etc.
These features will be accounted for, I just need to be sure these are the only features missing.

Ok, So instead of comparing id's we compare threads. Fine. This means I need a map of thread references instead of ids. If I have a thread reference and I want to check if it is the current active thread I can do the following? thread_ref == Thread(); As far as I understood calling the constructor without arguments returns the current thread. So I can compare that one with my thread references. That would be great! (I guess it is great) thx, Olivier.
