    [ https://issues.apache.org/jira/browse/TAP5-466?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12666971#action_12666971

See notes in TAP5-463 about the viability/safety of this concept.

>                 Key: TAP5-466
>                 URL: https://issues.apache.org/jira/browse/TAP5-466
>             Project: Tapestry 5
>          Issue Type: Improvement
>          Components: tapestry-ioc
>    Affects Versions:
>            Reporter: Howard M. Lewis Ship
>            Priority: Minor
> The concept here is similar to the proposed LazyDecorator, except that the method invocation
will be evaluated, in parallel, in a worker thread.  This implies that there's a service for
managing worker threads as well.
> Again, this only applies to methods that return an interface type (that can encapsulate
the future value) and throw no checked exceptions.
> The returned object would delegate to a Future object linked to excecution of the method
invocation in a worker thread.
