More specifically, it looks like the generator has finished acting on
all the incremental file-list chunks it has so far and is waiting for
the next one to arrive from the receiver, while the sender and receiver
are both waiting for the index of a file to transfer.  We should figure
out why the sender and receiver aren't supplying a file-list chunk or an
end-of-file-list indication.
