> TestHFlush.testHFlushInterrupted can fail occasionally due to a race: if a thread is
interrupted while calling close(), then the {{finally}} clause of the {{close}} function sets
{{closed = true}}. At this point it has enqueued the "end of block" packet to the DNs, but
hasn't called {{completeFile}}. Then, if {{close}} is called again (as in the test case),
it will be short-circuited since {{closed}} is already true. Thus {{completeFile}} never ends
up getting called. This also means that the test can fail if the pipeline is running slowly,
since the assertion that the file is the correct length won't see the last packet or two.
