Changes (by simonmar):

  * status:  new => closed
  * resolution:  => wontfix


Comment:

 The versions in base have been deprecated in 7.6.1, and we now recommend
 that people use the `SafeSemaphore` package instead.

 This leaves the way open for having a `concurrent` package in the future
 that would combine a number of useful concurrent data structures with
 things like `async`.
