class SimpleExecutionQueue extends PrettyPrinting with NamedLogging with FlagCloseableAsync
Functions executed with this class will only run when all previous calls have completed executing. This can be used when async code should not be run concurrently.
The default semantics is that a task is only executed if the previous tasks have completed successfully, i.e., they did not fail nor was the task aborted due to shutdown.
If the queue is shutdown, the tasks' execution is aborted due to shutdown too.
