> {{TimedSemaphore}} is a specialized Semaphore implementation that also has a timing component: In a configurable time period a given number of permits is available. Threads call the semaphore's {{acquire()}} method to request a permit. When no more permits are available {{acquire()}} blocks the calling thread. At the end of the time period the permits are restored, and all blocking threads are waked up.
> The main use case for this class is to provide a convenient means for controlling the load produced by a process. When used correctly, {{TimedSemaphore}} ensures that only a given number of steps (e.g. database queries, file operations, or computations) are performed in a specific time period. This may be useful for many applications.
> More information including a usage example can be found in the Javadocs of the class. Comments or suggestions for improvements are appreciated.
