I'm very much aware of that and I've tried pinning it down a few times, 
but failed to come up with anything conclusive. I plan to make a new 
effort in this context as the freezes have increasingly been annoying me.

Unfortunately latencytop only shows a blank screen when used with BFS, but 
I guess that's not totally unexpected.
