With Memcheck, great efforts were made, and continue to be made, to have
a very low -- essentially zero -- false error rate.  Feedback from users
showed that to be something that was regarded as very important.

So it seemed natural to do the same with Helgrind.  A pure h-b
framework gives no false positives for race-free programs, provided
it can see all the inter-thread synchronisation events.
