PROCEDURE DontOverflow(srd: StreamRd.T);
If srd.lo, srd.cur, and srd.hi are too high, adjust them downwards
to prevent them from overflowing. Increase srd.offset by
the amount of the adjustment. This should be called by the
class-dependent code whenever srd.hi is increased. The reader must
be locked when calling this procedure.
END StreamRdClass.
