  17 # Before that bug was fixed, starting an inferior in a non-main UI
  18 # would result in GDB saving readline's prepped terminal state as
  19 # gdb's "own" terminal state (i.e., target_terminal_ours state),
  20 # resulting in subsequent synchronous execution commands in the main
  21 # UI disabling input echo.
