> While adding some tests for the {{ThreadPoolMetrics}}, I discovered that the
> {{SEPExecutor}} does not release the blocked threads as it should.
> If the number of tasks added to a SEPExecutor exceed the max queue size. The
> threads adding those task will be block until enough space become available
> for all the blocked tasks. At this point all the blocked threads will
> released at once.
