Difference between Post and SendAsync
To add items to a block you can either use Post or SendAsync.
Post will try to add the item synchronously and return a bool saying whether it succeeded or not. It may not succeed when, for example, a block has reached its BoundedCapcity and has no more room for new items yet. SendAsync on the other hand will return an uncompleted Task<bool> that you can await. That task will complete in the future with a true result when the block cleared its internal queue and can accept more items or with a false result if it's declining permanently (e.g. as a result of cancellation).
