Hi,
I have just pushed major refactoring to the gateway module. Aside from
code reuse (there is still work to be done) between different gateway
implementations, and better scalability when recovering, it is the basis for
implementing the feature that reuses the work directory content when
possible. See how to upgrade if you use the FS gateway here:
