I am a semaphore that limits the number of simultaneous actions.

Builds and BuildSteps can declare that they wish to claim me as they run. Only a limited number of such builds or steps will be able to run simultaneously. By default this number is one, but my maxCount parameter can be raised to allow two or three or more operations to happen at the same time.

Use this to protect a resource that is shared among all builders and all slaves, for example to limit the load on a common SVN repository.
