* Config property jvmExitOnFatalError
* System.exit in case of fatal error, such as OutOfMemoryError
* Adjusted NonFatal extractor, ok with StackOverflowError, not ok with LinkageError
* Removed the actor null check in ActorCell
* Tried to add @SerialVersionUID(1L) but that removed static forwarders, due to https://issues.scala-lang.org/browse/SI-4804
* Added Serializable to UntypedActorFactory
* Removed some unecessary Serializable
Fixes an interesting "bug" in RandomRouter. Tests failed on my 12 core Linux box. After some investigation I found that it hanged randomly inside the SecureRandom seed generator.

Puzzled at first I Googled the problem and found this bug report: http://bugs.sun.com/view_bug.do?bug_id=6521844
In short it is designed to block on /dev/random (on Linux) when the entropy pool is empty until some "environmental noise is gathered".
From the Linux manual:
"Hanging at generateSeed is not a bug, since that's what was designed:
When the entropy pool is empty, reads from /dev/random will block until
additional environmental noise is gathered.
(Source: Linux Programmer's Manual, section 4)"
Fix was to switch to java.util.Random.
Fun one
