I think that it could be fixed in readline by doing the following when
reinstalling the old signal handlers:

  - block signals
  - call RL_CHECK_SIGNALS
  - restore old handlers
  - unblock signals


Readline could probably get most or all of the way there by modifying
CALLBACK_READ_RETURN to call rl_check_signals/RL_CHECK_SIGNALS after
calling rl_clear_signals and before the return. What do you think?
