You can try, as the bash devel branch does, to install the SIGWINCH
signal handler with the SA_RESTART flag. The readline code has always
installed its SIGWINCH handler with SA_RESTART, but when it restores
the bash SIGWINCH handler, it uses the flags bash uses, and until last
December those didn't include SA_RESTART.
