Comment:

 Yes; this is almost certainly causing lossage in linked connections.  The
 issue is that writing to a paired bufferevent can cause the data to get
 transferred immediately, so that checking right after to see if anything
 is sitting on the buffer won't actually do you any good.

 I think we can fix this one by checking dir_spool_src in
 connection_dir_finished_flushing().  See branch bug3814 in my public
 repository.
