Bug 342 reported distributor_autotest execution suspension
on aarch64 platform.
Issue was due to lack of synchronization among threads. Distributor
thread and worker thread may get deadlocked.
Fixed synchronization issue by adding barriers.
Another issue identified was in test case. Non-atomic operation on
stat value could cause value reset not been observed by worker thread
and mess counters. The issue was fixed by using atomic operations.

Hi David,
I had tested this previously, including performance comparisons
against original version on x86, and saw no performance degradation, so
I Acked it. I can re-ack on the latest version now.
Thanks,
Dave.
