Provide counting semaphores

[olbat]

First of all thank you for you great work, Ruby definitely needs a reliable concurrency library such as yours ...

It looks like there is no implementation of counting semaphores in your library.
It should be great to provide one since there is none in the Ruby core.

Some links that may be useful:

• The POSIX implementation
• ruby-core patch propositions

This sounds like a great addition. I expect we will add it to the feature list for the next release.

I am about to go on vacation for three weeks, after which I will be meeting some of the core contributors at RubyConf in San Diego. When I return we'll finalize the 0.8.0 roadmap.

@olbat Do you need this functionality soon?

[olbat]

@jdantonio No, it's not that of an emergency ...

@pitr-ch I forgot that we had this open issue. Thank you for closing it.
