Support for timeout on blocking dequeue

[mojoBrendan]

I needed this for my application and modified the unix semaphore implementation to support this.

Are you interested in adding more widespread support for this? I can create a pull request for you to look at if you want.

I always like pull requests! :-)

The reason it's not already implemented is that I wanted it to be completely cross-platform, and I don't have any Mac OS X machine to try stuff on. One blog post suggests using semaphore_timedwait, but I can't find reference to that function anywhere else on the web...

I suppose I could add timed wait support for only those platforms that support it. I'll take a look when I have some time.

Is the timed wait support for blocking dequeue available by now? :)

[cameron314]

Not yet. Been too busy. ETA early 2016.

This is now done. See issues #22 and #38.
