That's right, we ran into the same problem this morning during operator 
test time. When a user sends a request to "abort" a script the executor 
servlet sends a "halt" message to Barry's executor. The executor is 
written such that the script will not actually abort until the next 
source change which could be seconds, minutes or hours away. Until this 
is corrected it will continue to be a problem. Also, as Pat mentioned in 
her email, we found that the mib was generating acu commands even when 
the file was aborted and the executor stopped.
