Why does it show RMAN is still running...

Question

I am using RMAN in Oracle 11.2.
I tried kicking off RMAN a few times to test my script, and then did a kill -9 on the process numbers.
But I found out that RMAN was still running in the database, and was using a lot of System I/O (from what I could see in OEM).
I see the session in Toad and killed them from within Toad, and the system I/O dropped off.
I could also see in OEM that my RMAN processes were killed off.
So, first, why didn't the kill -9 actually kill the processes running in the database?
Next, when I still look in V$RMAN_BACKUP_JOB_DETAILS, it shows I have some jobs still running.
How do I terminate these processes?
I need to do this as soon as possible. Please help if you can.

There is nothing there any longer.
But it still shows up in V$RMAN_BACKUP_JOB_DETAILS.
