I realy think that freezing this library will have as consequence the freeze of at least these libraries: ThreadPool, AsynchronousExecutors, Threader/Joiner (both included for the moment in Interthreads), Active Object ...
There is nothing keeping these other libraries from using "futures". Nothing is frozen. In fact, most utility libraries are added to boost by slipping them into other boost libraries. There is a certain priviledge to being a top-level boost library. It needs to be reserved for libraries that have received the appropriate amount of peer review. That cleary did not occur here. I agree that if a "review" does not generate enough reviews, than it should be scheduled again, with refined review criteria to attract more reviewers the next time. That is how I am inclined to proceed. Adding concurrent programming libraries to boost without lots and lots of peer review is a mistake. It is an extremely difficult subject. Unless persuaded otherwise, those will be the instructions that I will be giving the "Review Wizards". //Tom
