It gets the internal omniObjRef part of an object reference.

It returns null when the object reference is nil. In your code, you
should check for nil before trying to set the timeout.

Having said that, the code ought to check. I've checked in a change so
that it throws INV_OBJREF if you try to set the timeout of a nil
object reference.
