What if you have two drives attached? Process 1 is writing to 181, process 2 is writing to 182. Process 2 ends and you are finished with 182. Process 1 is still running (syslog is piped to it - it isn't gonna end any time soon). How do you release the drive? Yes, you could DETACH it. But what if this is an LPAR?
