Yes, with one small difference: I wouldn't be calling ERR_get_error()
in the common case where SSL_get_error() returns SSL_ERROR_NONE, on
the theory that skipping that case represents no risk. I'm making a
concession to Peter E's view that that will calling ERR_get_error()
more will add useless cycles.
