I seem to understand it. `nested' is seen non-null value in the thread
_that executes the action_. In any other threads, the default null value
will be seen. And in the executing thread, after pending sends are
released, no user code will be executed, so no actions will be dropped.
Best Regards
Howdy group, I was reading the implementation of Agent -- Agent.java,
and have a question on nested send/send-off's.
When an action is being executed, send/send-off's are queued in the
persistent vector `nested':
static void dispatchAction(Action action){
LockingTransaction trans = Lockin
