Well, we are talking about s_client here... part of openssl executable. select() is used with the blocking sockets to make sure that, well, they don't block. If you call SSL_read on a blocking socket when select says it is readable you expect it not to block [forever]. Of course it might block if there is some data available on the underlying socket but not enough to complete SSL deciphering, but under normal circumstances it will only block until the rest of the record is received.
