Ah, this one has a much clearer problem - when I made the log-dirty
bitmap allocate pages from the p2m pool I introduced a path where the
log-dirty lock and the shadow lock can be taken in the wrong order. :(

I'll fix that now, but since it didn't show up in the other trace
there's at least one more bug out there somewhere. 

Cheers,

Tim.
