solver: add a TODO note about making this fully evented

Applying a 100+ patch series can be a pain and lead to a wayward
client monopolizing the connection.  On the other hand, we'll
also need to be careful and limit the number of in-flight file
descriptors and parallel git-apply processes when we move to an
evented model, here.
