we receive sigpipe when we write into the closed socket.
there is several ways to handle it:

signal(SIGPIPE, SIG_IGN) - platform independent
use flag MSG_NOSIGNAL with send() - linux
setockopt(NO_SIGPIPE) on osx
Linux solution requires access to each socket write which require BIO calls for openssl.
For now I'll use solution SIGPIPE and openssl #1.
