commit a87c159f19e998bba660ceba9d01c5fc58bfa60b
Author: Richard Levitte <levitte at openssl.org>

    Fix freeze in config's interrupt trap with some shells
    
    With bash and zsh, the trap on the 5 second read does respond, but
    doesn't break out of the read.  What's worse is that it takes away the
    5 second timer, and therefore has the read hang indefinitely and
    (almost) unbreakable.
    
    Having the trap do 'exit 0' after reseting the tty params has it break
    out of read and continue with the configuration.
    
    Other shells do not appear to have the issue described here, but
    neither does the extra 'exit 0' appear to harm them.
