The max size of queue is `1` by default.
So, `try_flush` will be called with `flush_thread_interval`, not
`flush_thread_burst_interval`.
The previous test code assumes that the interval is 0.1s, but
it was actually 1s.
This would be the cause of the occasional failure.
test: #write is called per value combination of variables, per flush_interval & chunk sizes, and buffer chunk is purged(BufferedOutputTest::buffered output feature with variables):
assert{ @i.buffer.stage.size == 0 }

The max size of the buffer queue is
1by default.So,
try_flushwill be called withflush_thread_interval, notflush_thread_burst_interval.The previous test code assumes that the interval is 0.1s, but it was actually 1s.
This would be the cause of the occasional failure.
