Threads: Barrier destuction, ??? for references

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?

Thanks,
Dave
