Isn't it a bit of a "shotgun approach" of doing a find of all files in 
the whole forest to find the lock files in .hg? It seems much speedier 
to just check the .hg directories in the sub repos; they are just a few 
and are known to the forest script.

I'm worried that this might be unneccessary slow on slow system.
