171 C exchUsesBarrier - TRUE if we use a call to BAR to do sync.
172 C between processes. On some machines we wont
173 C spin on the Ack setting ( the T90 ),
174 C instead we will use s system barrier.
175 C On the T90 the system barrier is very fast and
176 C switches out the thread while it waits. On most
177 C machines the system barrier is much too slow and if
178 C we own the machine and have one thread per process
179 C preemption is not a problem.
