well, "traditional" join provides some special/strong
thread termination thread guarantees:

"For instance, after pthread_join() returns, any
 application-provided stack storage could be reclaimed."

IMHO Boost.Threads should not relax it even if it would
allow to call join multiple times (and on multiple threads).
because it would provide an extra C++ thread object to
"join with". that is why i think "join" name is justified.
