    if ((cnt = sysReadFD(fdptr, (char *) buf, 1)) != 1) {
        if (cnt == 0) {
            return -1; /* EOF */
        }
        if (errno != EINTR)
            SignalError(0, IO_EXCEPTION, "read error");
    }
    return buf[0];

In the unlikely case that errno == EINTR, we return the uninitialized value
of buf[0]. This is bad. readBytes does not have this problem.
