read.c::tds_get_string() contains what looks like a silly loop:

        char temp[256];
        char *p, *pend;
        /* ... */
        while (string_len > 0 && p < pend) {
                in_left = string_len > (sizeof(temp) / 2) ? 
                        (sizeof(temp) / 2) : string_len;
                tds_get_n(tds, temp, in_left * 2);
                p += tds7_unicode2ascii(tds, temp, in_left, p, pend - p);
                string_len -= in_left;
        }
        return p - dest;

Basically, if the input string is more than 128 characters, we call
tds_get_n() and tds7_unicode2ascii() in 128-character chunks.  

Why do we do this?  I can't see any reason.
