@aloiscochard, @puffnfresh thanks, will take a look.

scalaz.concurrent.Task is not very good. Using just a reasonable IO type, it should be possible to subsume Task's use cases with some uses of MVar-like atomic-references. For example:

I agree, and that is the route we are going with FS2's Task type (which I suppose could be renamed to 'IO'), which implements MVar-like references and then uses that to implement async (and lots of other operations, like parallelTraverse, as well as all the concurrent stream operations of FS2 itself): https://github.com/functional-streams-for-scala/fs2/blob/topic/redesign/core/src/main/scala/fs2/Async.scala#L75
