No, but lock is problem in itself. If ioctl locks the sw_demux, wanting
to update something, during that very moment, vpeirq wants to use sw_demux 
it will find it locked and would be forced to sleep but as tasklets can't
sleep that would lead to oops schedule() in interrupt i guess.

Maybe I'm too cautious, or don't know the completeness of the source
that's something Ralph was talking about regarding stability issues.
