EINTR happens when a signal gets delivered. This also includes SIGALRM. Thus just ignoring EINTR and continuing would break timeout handling using an ALARM handler. A simple application does not deal with signals and it will not get signals and thus no special handling of EINTR needs to be done. But in my opinion there is an explicit SIGCHLD handler in the code not shown so the application explicitly asks for signals and therefore has to properly deal with these. While IO::Socket::SSL->new cannot be restarted the proper way is to just create the SSL socket without handshake as documented and then explicitly do the handshake with connect_SSL or accept_SSL. These operations can be restarted. BTW, this is true for IO::Socket::INET too.
