>
> {{LibeventSSLSocketImpl::create}} is called whenever a potentially
> ssl-enabled socket is created. It in turn calls {{openssl::initialize}} which
> calls a function {{reinitialize}} using {{os::setenv}}. Here {{os::setenv}}
> is used to set up SSL-related libprocess environment variables
> {{LIBPROCESS_SSL_*}}.
> Since {{os::setenv}} is not thread-safe just like the {{::setenv}} it wraps,
> any code calling functions like {{os::getenv}} (via or {{os::environment}})
> concurrently with the first invocation of {{LibeventSSLSocketImpl::create}}
> perform unsynchronized r/w access to the same data structure in the runtime.
> We usually perform most setup of the environment before we start the
> libprocess runtime with {{process::initialize}} from a {{main}} function, see
> e.g., {{src/slave/main.cpp}} or {{src/master/main.cpp}} and others. It
> appears that we should move the setup of libprocess' SSL environment
> variables to a similar spot.
