The only way I'm aware of is to watch the process listings for  
programs that are in the 'D' state. Also keep an eye on 'vmstat 1' -  
it might show you something interesting such as a very high number of  
pages being swapped in/out of VM as would be expected of a rogue  
process trying to write random gibberish over random locations of  
addressable memory.

AFAIK, there is not yet any way in Linux to discern which process is  
actually causing the high I/O apart from killing random processes and  
watching for the high I/O to stop.
