* data in a callback.

* This implementation may:
|
|
*
|
|
* 1) Coalesce identical prompts. This means prompts that are guaranteed to

* want the same auth information from the user. A single prompt will be
|
|
* shown; then the callbacks for all the coalesced prompts will be notified
|
|
* with the resulting auth information.
|
|
* 2) Serialize prompts that are all in the same "context" (this might mean
|
|
* application-wide, for a given window, or something else depending on
|
|
* the user interface) so that the user is not deluged with prompts.
|

*
|
|
* @throw
|
|
* This method may throw any exception when the prompt fails to queue e.g
|
|
* because of out-of-memory error. It must not throw when the prompt
|
|
* could already be potentially shown to the user. In that case information
|
|
* about the failure has to come through the callback. This way we
|
|
* prevent multiple dialogs shown to the user because consumer may fall
|
|
* back to synchronous prompt on synchronous failure of this method.
