This seems OK, but could you describe in more detail what this patch does and why it's necessary? What problems does it fix? How do the problems manifest themselves? 

Thanks,

It seems like the old code was being very cautious and limiting the number of loads that could be sent to the lsq to the current free - the number dispatched. This change seems to actually check how many memory references were dispatched. It makes sense. Anyone have any thoughts about committing it?
