I'm trying to define what could/should happen if a barrier is
destroyed while other threads are still wait()ing on the barrier.
POSIX threads state that the impact on those threads is undefined.
I wanted to do some more reading on cancellation mechanics for
barriers to see if some solution that would throw a controlled
exception out of wait() in this case is possible.
Most of the references I can find to barriers on the web are from the
massively-parallel architecure field, and implementation strategies
for these architectures....
Does anyone know of the "seminal" paper for this concept?
