179 C exchUsesBarrier - TRUE if we use a call to BAR to do sync.
180 C between processes. On some machines we wont
181 C spin on the Ack setting ( the T90 ),
182 C instead we will use s system barrier.
183 C On the T90 the system barrier is very fast and
184 C switches out the thread while it waits. On most
185 C machines the system barrier is much too slow and if
186 C we own the machine and have one thread per process
187 C preemption is not a problem.
