It's pretty hard to ignore a process with a name that ugly ;-)

How about just ksoft0 ?  Or kirq0?

I don't see the sense of trying to encode a whole sentence into the 
process name.

(Peter, this handles softirqs in a more predictable way by allowing the 
scheduler to take care of any softirq that can't conveniently be 
executed immediately.  Among other benefits, this approach eliminated 
the need to check for and execute pending softirqs on exit from system 
calls.)
