It means that some merges you'd like to work (and think it's obvious how 
they should work), won't work.

[The reason is to do with invertibility of commutation, which is one of 
the properties of patches that leads to the guarantee that you get the 
same repo from the same set of patches no matter what the sequence.]

This might be caused by a dependency of some form, or it might be 
caused by darcs send being too eager at picking up context. I'm not sure 
what darcs send does to decide what the context should be.
