[CHANGES]
* Rename 'dependent' futures to 'convergent'

should report as a failed Future, not throw exception to caller
0.29 2014/07/17 12:18:12
[CHANGES]
* Added Test::Future

->and_then / ->or_else warn once

cancelled. (Partially fixes RT96685)

to return immediates

strong references. This old code was, however, broken.
