Any updates or results?

Suggest creating a test case that demonstrates the getIsa criteria:

- when a process is detached the isa is invalid
- when a process is attached the isa is valid

by transitioning a process through attached and detached events checking that it
gets its state changed

Added TestCase to check memory is null when not attached and not null when attached.

        * TestMemory.java: Added.	
	* TaskState.java (Attached.transitionToRunningState): Changed to notify static
Task observable.
	(detaching.handleStoppedEvent): Ditto.
	* Task.java (ObservableXXX): Made static.
	(taskStateAttached.update): Ditto.
	(taskStateDetached.update): Ditto.
	(Task): Removed add observer from here and made static so any task that
attaches gets data filled.

More test cases that should be looked at:

Test that isa is a singleton. (Unless switching between 32 and 64 bit execs)
Test switching between 32 and 64 bit execs.
Test Attach, Detach, Attach agan, (Detach again), etc.
Test Attach, create attached child process.

TestIsa.testAttachDetachAttachAgainDetachAgainAtachAgainAgain().

> Test Attach, create attached child process.
TestIsa.testAttachedCreateAttachedChild(), testAttachedCreateAttachedClone() and
