 From what I understand, it will /not/ be able to perform the kinds of 
tasks that -9 specifies.  E.g. -9 represents a collection of tuning 
parameters, including such things as "and use a gigantic dictionary to 
store bit sequences that may repeat, and hence be represented by 
shortened codes".  If you want a -9-sized dictionary, and you can't get 
it...xz shouldn't fall back to a -8-sized one.
