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


Comment:

 Fixed, I hope.  It looks like small delays aren't as accurate on OS X as
 they are on Linux, but in any case this test was fragile so it's a good
 thing to fix it.  It might be a good idea for someone to look into why the
 delays weren't accurate on OS X, but it may just be that there's only a
 20ms resolution for the `select` timeout or something.
