ThreadPool

java.lang.Object
- org.jgroups.util.ThreadPool

```
public class ThreadPool
extends java.lang.Object
```
Maintains a set of ReusableThreads. When a thread is to be returned, all existing threads are checked: when one is available, it will be returned. Otherwise, a new thread is created and returned, unless the pool limit is reached, in which case null is returned. Creates threads only as needed, up to the MAX_NUM limit. However, does not shrink the pool when more threads become available than are used.

To do:

Shrink thread pool if threads are unused after some configurable time.
