Balancer (SureFire JUnitCore Runner 3.2.1 API)

```
public interface Balancer
```
The Balancer controls the maximum of concurrent threads in the current Scheduler(s) and prevents from own thread resources exhaustion if other group of schedulers share the same pool of threads.
If a permit is available, acquirePermit() simply returns and a new test is scheduled by Scheduler.schedule(Runnable) in the current runner. Otherwise waiting for a release. One permit is released as soon as the child thread has finished.
