+When a keystroke requires a network transaction, the transaction often
+takes place in a `handle_keypress()` method, which means the display
+isn't updated until that method returns, because only `Tui` can do
+display updates. But some network transactions take noticeable time,
+so it would be nice to do an immediate display update to indicate that

+involve actual code restructuring, since in Rust it's not trivial to
+just casually call back to the top-level thing.
