Hey, is there a better way to create properties where getters and setters are protected using a lock?

  private val lock = ReentrantReadWriteLock()

  fun getName(): String {
    lock.readLock().lock()
    try {
      return name
    } finally {
      lock.readLock().unlock()
    }
  }

jschneider: First of all, your `fun getName` should really be a `val name` with a getter. And then check out the extension functions on `ReentrantReadWriteLock` that the standard library provides: <http://kotlinlang.org/api/latest/jvm/stdlib/kotlin.concurrent/java.util.concurrent.locks.-reentrant-read-write-lock/index.html>

so something like 
```
import java.util.concurrent.locks.ReentrantReadWriteLock
import kotlin.concurrent.*

class K {
    private val lock = ReentrantReadWriteLock()
    var name = "initial"
        get() = lock.read { field }
        set(new) = lock.write { field = new }
}
```
