TSSLSocket::close should handle exceptions from waitForEvent because it is called by the destructor.

~TSSLSocket calls TSSLSocket::close, which calls TSSLSocket::waitForEvent.

TSSLSocket::waitForEvent() throws an exception in some cases:

• Unexpected error
• InterruptListener has been written to
• poll() times out

TSSLSocket::close should log the error but not emit an exception, similar to how it handles errors from SSL_shutdown.
