* This is a test class that fails on centos 64bit. On working machines, it runs
* and always prints out 100, but on centos it will randomly print out 0. Note
* that the test as written is specific to a quad store (it makes the quad store
* assumption about the context position). (This issue has been linked to a bug
* in {@link BlockingBuffer#add(Object)}, where it was failing to test the
* return code from
* {@link BlockingBuffer#add(Object, long, java.util.concurrent.TimeUnit)} and
* the latter had a bug in its timeout logic.)
