I'm no SCSI guru, but I don't understand: If you are sending a command abort (I 
guess this is what we are talking about, or is it a target abort?) to a LUN, 
think it's reasonable to wait for the command to abort before sending any other 
commands to the target/LUN. Are your referring to different LUNs/targets when 
saying "new or other tasks"?
